The purpose of this commit is to prevent saving to a form view
if you have created and edited a new invalid record in an x2many.
How to reproduce
- go to a form view with an x2m
- create a new record with at least one required field empty in the x2m
- edit another field than the required one
- click on the save button
Before this commit:
- The view is switched to readonly mode and the new record is deleted.
After this commit:
- The view stays in edit mode, the new record is not deleted and
a notification indicating invalid fields is displayed.
