Bug report #14983
relation editor widget in custom form can cause crash
|Affected QGIS version:||master||Regression?:||No|
|Operating System:||Easy fix?:||No|
|Pull Request or Patch supplied:||No||Resolution:||fixed/implemented|
|Crashes QGIS or corrupts data:||Yes||Copied to github as #:||22932|
If the qgisRelation property of the QgsRelationEditorWidget is not defined correctly in the .ui file then opening a custom attribute form with a value relation widget causes QGIS crashes. This does not happen in 2.8.9 but does happen in 2.14.3 and master.
I have only tested this on Windows 7, using OSGeo4W 64-bit.
This is possibly related to bug report #14956.
