When you try to empty a date or datetime field, you get a traceback
saying that 'clone' and 'isSame' are not functions.
This error occurs when you empty the field because the value is 'false'
and you cannot call 'clone' or 'isSame' on false.
To fix this, we ensure that value is not false before calling these
methods on it.
This bug has been introduced in rev: https://github.com/odoo/odoo/commit/c32724eae06c987e74a0600f1669696e499edc33
The 'mode' attribute can be used for x2many fields to force the
view mode. Before this rev., it was ignored and if a tree view
existed in the view description, it was selected by default.
This was mainly a problem in mobile as in this case, kanban views
are prefered, and the data_manager forces the mode to be kanban,
so the data was fetched according to the kanban view fields, but
later on the list view was instantiated instead of kanban by the
x2many field, so it crashed if both views didn't share the exact
same fields.
There were several issues with this widget, and the way the model
handles its requests (mainly the removal of values).
It crashed for instance on the product form view when the user
updated the routes field (field route_ids in tab inventory).
The client must receive the tzOffset to apply this on all hours.
To use the date picker we must change the date to apply the change
in the user's tzOffset, without this change the result is wrong.
For datetime widget we must change like it to avoid max stack error.
The server send the tzOffset, if it's undefined, by default the client
use the browser time offset.
Every test are change to use tzOffset.
A test is added in calendar to use the click by position for the
fullcalendar lib. This test create and drag and drop an event to check
timezone error and error when we use default value in the context.
Use formating date like 2026-04-04T08:00:00Z instead of 2026-04-04 08:00:00
is important for phantomjs, because it's crash without information if the
formating is not the standard format.
For the parsing, when the client receive a server date the date is utc
formating but when it's parsed from the client is in the user's timezone
