Let's start with a basic One2many relation, a class Parent and a class Child.

When I open a Parent form and try to create a new Child from the one2many popup opend by the "child_ids" form field, the parent_id field is not selected with the current open Parent from the window view ! I have to retrieve it in the parent_id selection field to re-select it.

Is there a way to do this autoselection ?
