They can be an issue for embedded forms.

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 2015-10-01 23:53 GMT+02:00 Luca Lanteri <mesca...@gmail.com<mailto:mesca...@gmail.com>>: Hi, now I'm already using the python logic but my code is terrible and I have a lot of crash problem. Now that I using your example all is easier and seem to worsk fine. I owe you one beer. Many many tanks ! Luca 2015-10-01 22:23 GMT+02:00 Blumentrath, Stefan <stefan.blumentr...@nina.no<mailto:stefan.blumentr...@nina.no>>: Hi Luca, Sounds like a case for Python logic! General principles are explained here: http://nathanw.net/2011/09/05/qgis-tips-custom-feature-forms-with-python-logic/ Also nice, and probably exactly what you are looking for: http://medspx.fr/blog/Qgis/cascade_forms/ Cheers Stefan From: qgis-user-boun...@lists.osgeo.org<mailto:qgis-user-boun...@lists.osgeo.org> [mailto:qgis-user-boun...@lists.osgeo.org<mailto:qgis-user-boun...@lists.osgeo.org>] On Behalf Of Luca Lanteri Sent: 1. oktober 2015 22:07 To: qgis-user <Qgis-user@lists.osgeo.org<mailto:Qgis-user@lists.osgeo.org>> Subject: [Qgis-user] QGIS - value relation widget Hi to all, I need to build a form when the value of a combo are filtered basing on the value of anoter combobox. I have a first combo where I choose the region and a second with the municipalities. I need that the second combo shows only the municipalities of the choosed region. I tried to use use the widget "relationship value" with the a filter like classe_munic = attribute($currentfeature, 'classe_munic') without any success. Has anyone ever done something similar?
