[Qgis-developer] [Qgis-user] QGIS - value relation widget

[Luca Lanteri]

Sadly, after further test I discover that the crashes remain, so I think it
is a qgis bug and not a problem in my code.
The problem happens when I put my custom form into a subform widget
(QgsRelationEditorWidget). If I add a new record in the subform and I move
to another record using the left column QGIS crashes. It seems to be a more
general problem because the crash appears also when I add some simple
control that modify the object in the form.

I can open a ticket and add some test data.
If it is a minor bug and it could be resolved easily I really offer a pizza
and a beer to resolve it.

All the best
Luca
