This error occurs when clicking the `Reset Selected Work Entries` button while there are no employees in the work entries.

Steps to reproduce:
- Install `hr_payroll` module
- Payroll > Work Entry > Remove `Active` Filter
- Select any cell and click on the reset button

Traceback:
`KeyError: 'employee_id'`

This error occurs when the `Reset Selected Work Entries` button is clicked without an employee, causing `employee_id` to be missing at [1].

Solutions:
- Raise a validation error when no employee is selected and the `Reset Selected Work Entries` button is clicked.
- Fix the error that occurs when clicking the `Set` button to add or replace a work entry.
- Fix the error that occurs when the `Active` filter is enabled and the `Reset` button is clicked.

Currently, editing a posted `miscellaneous` journal entry in Chile 
localization incorrectly raises a validation error.

**Steps to reproduce:**
- Install the `l10n_cl` module and switch to the `CL company`.
- Go to Accounting > Accounting > Journal Entries.
- Create a balanced entry using the `Miscellaneous journal `and `post` it.
- Reset it to draft, modify the `name`, and try to `save` it.

**Observation:**
`Validation error`: `The DTE document number (folio) must contain only digits.`

**Root cause:**
At [1], the constraint validation is applied to all journal entries in 
Chilean companies, including `miscellaneous` journals. However, 
`miscellaneous journals (move_type = 'entry')` are not linked to Chilean 
electronic documents, so the numeric folio validation should not apply to them.

**Fix:**
This commit ensures that the validation is not raised for `miscellaneous` journal 
types by excluding miscellaneous journals from the numeric folio validation constraint.

From version 19.1, a new image pop-up functionality was introduced. Now, when an image is added to the website,
and the pop-up image option is enabled,
Clicking the image raises a traceback.

To reproduce the issue:
- Connect to a saas~19.1 runbot,
- open the website module, and enter edit mode.
- Add an image, click it, and enable the pop-up image option.
- Save the changes.
- Clicking the image will display the pop-up, but a traceback will appear behind it.

When opening an SO in POS that has a product tracked by lot that is split into several location, the lot number will only appear in one of the line and not the others

Steps to reproduce:
-------------------
1. Create a Product A tracked by lot, create lot 111 and add 1 unit to location A and another one to location B
1. Create a sales order
2. Add two units of the product to the sale order
3. Confirm the sales order
4. Open the transfer, make the transfer retrieve the product from several location with the same lot.
5. Save the transfer
6. Open the sales order in POS
7. Load the SN/lots
-> Two line of qty 1 appear for the product A but only the first one has the lot number

Additional Issue:
8. Change the number of the product for the first line to 2 and erase the second line
9. Confirm and Pay
10. Close POS
11. Open move lines for this product (Inventory>product>In/out)
-> It moves 2 product from one location (when there is only product)

Observation:
-------------
When loading the SO in POS, we will retrieve the SO: https://github.com/odoo/odoo/blob/cb1f5d9c6db64b9ace9b7aa46bd6f94e4462176b/addons/pos_sale/static/src/app/order_management_screen/sale_order_management_screen/sale_order_management_screen.js#L104 While retrieving the SO, we will also retrieve the SOL, with additional information: https://github.com/odoo/odoo/blob/d9b2e5ee730a4e79586bfd3f09adfb794d2dc1f3/addons/pos_sale/models/sale_order.py#L79 -> Issue is that when several moves_line have the sale lot_id.name, their quantity will be overwritten.

Addition Issue :
When closing pos, all the move will be processed, when processing those moves, the origin only check if the quantity is more than 0 and not if there is enought units. https://github.com/odoo/odoo/blob/cb1f5d9c6db64b9ace9b7aa46bd6f94e4462176b/addons/point_of_sale/models/stock_picking.py#L293-L297

This PR hides the "Custom Url" field in the "Search Engine Optimization" when the URL of the current page do not contain any editable slug. Previously, this field could be filled when the URL did not contain any modifiable slug. However, the value was not take into account since the route of the page did not expect slug.

Reproduce:
With an admin user, activate the website editor on an appointment page. Clicking on "Optimize SEO" in the "Site" dropdown menu, a form containing the "Cutsom Url" field is displayed. This field should represent the current page's URL but with fillable field instead of the editable URL part. In this case, this is not correct as the URL is repeated before and after the fillable field, which does not represent the current URL. Also, the URL is not modified with the value entered in the fillable field.

After the fix:
The "Custom Url" field must not be displayed when URL does not contain a customisable slug.

Have a grouped list view with no aggregate fields. Before this commit, the colspan of the first `th` in group header rows wasn't optimally computed. These `th` can span to the very last cell (excluded), which may contain a cog menu. However, they only spanned to the second to last cell. As a consequence, in a list with only 2 columns, e.g. a handle and a name, the groups' name only got a few px available, and were hence cropped.

The issue came from successive reworks of the group header row, leading to the pager being finally moved from its own column (after the last aggregate column), to the group name cell (with ms-auto).

The logic is easier now, as a group header row looks like this:
- a single `<th colspan="n">` (n >= 1) to display the group name: spans to the first aggregate column excluded or to the last cell excluded if no aggregate (colspan + 1 if rows have selectors)
- one `<th colspan="1">` for each aggregate column
- optionally one `<th colspan="m">` (m >= 1) for all columns after the last aggregate column
- a single `<th colspan="1">` for the potential cog menu (optional dropdown column)

Safari does not reliably set `KeyboardEvent.isComposing` during IME composition (e.g. Korean). As a result, the search value was processed too early and got cleared while composition was still in progress.

Interestingly, the issue could not be reproduced with the Japanese keyboard, which appeared to behave correctly. See [1].

This commit introduces a short delay before closing the autocomplete. On iOS, the IME temporarily triggers a Backspace event to remove the previously composed character before inserting the updated one. This Backspace incorrectly causes the autocomplete to close. With this change, we wait briefly (10ms) before closing it. If a new input event is received during that delay (corresponding to the newly composed character generated by the IME), the close action is cancelled.

This ensures that the autocomplete remains open while the IME composition process completes.

Steps to reproduce:
- Configure a Korean keyboard on an iPhone
- Open a Sale Order
- Focus the search bar
- Type a character, then type a second one to combine them
- The search input value gets reset

Version : saas-18.4+e

Steps to reproduce
------------------
Create a product and add a line in the purchase tab with a “Vendor Product Name” and/or a “Vendor Product Code”.

Create a purchase order for this product with the right vendor and confirm it.

Go to the delivery receipt, the vendor code and/or name are added twice in the description.

Why is it happening
------------------
The _compute_description_picking method from stock.move, which is overridden in purchase_stock module, adds the vendor code and name to the description. However, if no description_picking has been set on the product, the description is already defined as the vendor code and name.

Solution
------------------
I propose to remove the code and the name from the vendor_reference variable if the original description already contains them.

Steps to produce:
---
- Install `website_sale` module.
- Go to website > open editor.
- Add an image snippet to the homepage.
- Click on the image and enable `Pop-up on Click`, then save.
- Click on the image.

Traceback:
---
`TypeError: Cannot read properties of undefined (reading 'length')`

Root cause:
---
- In the `setup` method, when the image is not part of a carousel,
  the element `.carousel-indicators` does not exist. As a result,
  `indicatorEl` is null, and the guarded block(at [1]) is skipped.
  Because of this, `this.liEls` is never initialized.
- Later, when the `onSlidCarousel` method is executed,
  its internal condition evaluates and find `liEls` as null and
  then `hide` method is called(see [2]).
- Inside the `hide` method, the code attempts to iterate
  over `this.liEls`(see [3]).

Solution:
---
- Initialized `liEls` in `setup()` to ensure it is always defined.
- Added a length check in `onSlidCarousel()` to execute the logic
  only when `liEls.length > 0`.
- This prevents this.page from being computed using invalid
  values and avoids it being set to `NaN`.
- Additionally, as requested by the boje(po), hide the popup
  on click setting on product images.
  
**Alternative approaches:**

1. We can also call the `onSlideCarousel` method from `setup`
    when multiple images are present.
2. Also, we can add a simple check inside the `onSlideCarousel`
    method to ensure that `liEls` is defined before proceeding.

In Taiwan e-invoicing, B2C customers can request a paper copy of their invoice. When selected, the "Invoicing Info" step—which collects data like donation codes or carriers—should be skipped as it is not applicable to physical copies.

Previously, this logic failed during guest checkouts because the partner initially associated with the order is an archived public user. The persistent partner is only created/assigned after the address form is submitted.

This commit:
- Overrides `_create_or_update_address` instead of `_handle_extra_form_data` to ensure the paper format preference is saved on the correct, newly generated partner.
- Updates `_prepare_address_form_values` to correctly load existing preferences from the partner for registered users.
- Ensures the `l10n_tw_edi_is_print` flag on the Sales Order stays in sync with the partner's preference.

Steps to Reproduce  
------------------  
1. Open the Planning Gantt view.
2. Click a cell that belongs to a resource with **no** scheduled shifts.  
3. The Plan dialog opens with an empty list.  
  
Issue  
-----  
A previous change  keeps the clicked resource in the dialog context; the Gantt 
model turns it into a default search filter, so only shifts already linked to 
that resource are shown. Unassigned shifts are therefore hidden, preventing 
planners from assigning them by role or availability.  
  
Current Behaviour  
-----------------  
The Plan dialog is always filtered by `resource_id`, which returns no results 
for unscheduled resources, even when they have the right roles.
  
Expected Behaviour  
------------------  
The dialog should list all unscheduled shifts that match the resource’s roles, 
or every unscheduled shift if the resource has no roles, while still preserving
full context for scheduling once a shift is selected.  
  
Fix  
---  
Remove the automatic resource filter from the dialog context in 
`getSelectCreateDialogProps()`. This prevents the unwanted search restriction; 
role defaults remain, so the dialog now displays the correct shifts.

…bcontracted

**Problem:**
Landed cost added on the receipt of a subcontracted product
do not increase the valuation of the product and do not create 
account move lines.

**Steps to reproduce:**
- create a tracked product with avco perpetual category
- create a subcontracted bom for this product with no comp
- create and confirm a PO for 10 unit of this product at a unit price 
of 1$ with the same partner as the subcontractor of the bom
- validate the receipt
- navigate to inventory/operations/adjustments/landed costs
- create a new landed cost
- select the receipt from the PO
- add a landed cost of 10$ and validate
- navigate to inventory/reporting/stock
- search for your product and click on the unit cost

**Current behavior:**
1) the valuation of the product was not increased by the value 
of the landed cost
2) open journal items : no account move lines were created for the 
landed cost

**Expected behavior:**
1) the valuation of the product should have been increased:
in the unit cost view, the SBC move should have gone from a 
value of 10 to 20
2) account move lines should have been created with a value 
of 10

**Cause of the issue:**
both issues come from the fact that when creating the 
stock valuation adjustment line, the move linked is the receipt move
when it should be the move of the subcontracted MO linked to the 
receipt.

**fix:** 
if we create the adjustement line with move_id as the move of the MO
(instead of the move of the receipt as it is the case currently) : 
when button_validate is called on the landed cost : 
- when using the remaining quantity, it will be the correct one 
(in our case 10, instead of 0 for the move of the receipt because it's 
actually an internal move) so the account move line are going to 
be created
https://github.com/odoo/odoo/blob/9c85d7265d7b1ca0b212f46c20aa1e8119c33a22/addons/stock_landed_costs/models/stock_landed_cost.py#L129-L130

which solves problem 2) 

-  when calling _set_value on the move (which will be the move of 
the MO thanks to this fix), 
https://github.com/odoo/odoo/blob/064407d32f998ceb08601f9e0a6356c94ad10347/addons/stock_landed_costs/models/stock_landed_cost.py#L152
get_value_data will call _get_value_from_extra,
https://github.com/odoo/odoo/blob/9c85d7265d7b1ca0b212f46c20aa1e8119c33a22/addons/stock_account/models/stock_move.py#L392
which uses _get_landed_cost to fetch the landed cost
https://github.com/odoo/odoo/blob/9c85d7265d7b1ca0b212f46c20aa1e8119c33a22/addons/stock_landed_costs/models/stock_move.py#L18
before this fix the landed cost created from the receipt were linked to 
the receipt move so they were not fetched inside _get_landed_cost
which caused problem 1) but now the move_id of the adjustment lines 
is the move of the MO so they are fetched inside _get_landed_cost
https://github.com/odoo/odoo/blob/9c85d7265d7b1ca0b212f46c20aa1e8119c33a22/addons/stock_landed_costs/models/stock_move.py#L7-L12
So now the adjustment lines do impact the valuation of the move of 
the MO which solves problem 1)

Issue
=====

The fiscal position defined on a partner was not properly isolated per company, leading to cross-company inconsistencies and errors.

Steps to Reproduce
==================

1. Install `industry_fsm_sale` and `l10n_br`.
2. In the US company:
   - Create a Brazilian customer.
   - Set a fiscal position on the customer.
3. Switch to the Brazilian company:
   - Open the same customer.
   - Set a fiscal position on the customer.
4. Still in the Brazilian company:
   - Create a task for that customer in the Field Service app.
   - Add a product to the task.

Result
======

An error is raised because the fiscal position from the US company is used, which is not valid for the Brazilian company.

Root Cause
==========

When reading the fiscal position from the partner, the value is fetched in the environment of the company in which the partner record was originally created (US company). If no company is explicitly specified, the fiscal position is read in that original environment, even when the user is operating under the Brazilian company.

Solution
========

Explicitly enforce the current company context when reading the fiscal position from the partner to ensure the correct company-specific value is used.

1. Install l10n_mx and l10n_mx_hr_payroll modules
2. Switch to INNOVACION VALOR... company
3. Go to Employees and open Cecilia Miranda Sanchez
4. Go to Payroll tab, set the end of the contract to Jan 31 and save
5. Create a new contract from Feb 1
6. Go to Payroll > Payslips > Payslips and create a new pay run
7. Select Salary Structure 'Mexico: Regular Pay', Pay Schedule 'Bi-weekly' and Period 'Jan 1 -> Jan 15'
8. Click on Continue, select Cecilia and click on Select
9. An error is thrown

Problem:
In `_compute_integration_factor` we try to compute the number of years the employee has worked by accessing the start date on the employee but this date might be earlier than the start date of the employee's current contract if the employee has changed contract. This will throw an error when we try to access the holidays count for 0 year because `payslip._rule_parameter('l10n_mx_holiday_tables')` doesn't have an entry for 0

Solution:
Use the start date of the first contract of the employee, take gaps in between the employee's contracts into consideration to correctly compute the number of years worked

There were 2 issues when `serverDateTime` was lower than `lastConfigChange` which triggered a reset on the indexedDB. The first issue was that we would try to await dbInstance.deleteDatabase request. But it returns a request object and then executes the delete asynchronously. This would cause a race condition on the init where we would trigger the init of the indexedDB at the same time as we were trying to delete it and it would hang for ~10 seconds before finally launching the POS.

The second more important issue is that after the reset there is a `localData = []`. This would cause the line in `synchronizeServerDataInIndexedDB` `JSON.parse(JSON.stringify(serverData));` to return an empty array so no new models would get created in the indexedDB and the POS would launch with an empty indexedDB.

This commit changes the `indexed_db.reset()` method to return a promise and awaits it before reinitialising the indexedDB. And resets the `localData` to `{}` which fixes the `synchronizeServerDataInIndexedDB`

Steps to reproduce:
- Open the website shop page in edit mode.
- Drag and drop a block in the shop header dropzone.
- Save the page and re-enter edit mode.
- Check the shop header dropzone message.
=> The custom message is replaced by the default one.

Before this commit, `SetupEditorPlugin.cleanForSave()` removed
`data-editor-message` and `data-editor-message-default` on the saved
HTML clone, including custom messages defined in website templates.

This cleanup was originally introduced in `web_editor` in [1]. Since the
builder refactor in [2], website page saves now use the shared
`html_builder` save cleanup flow and wrongly inherited that behavior,
which introduced this regression in website.

This commit removes that cleanup from `html_builder`, as it does not
provide useful value in this save flow and drops custom dropzone
messages.

After this commit, custom dropzone messages are preserved after saving
website pages.
