Variant Configuration: Selection of "None" Alternative for AlternativeFeatures causes an Exception
There was a class cast exception for a corner case in the variant configuration dialog.
Testing instructions:
- Create/open a AF3 Project with a FeatureModel that contains an optional (!) AlternativeFeature
- Right-click onto the FileProject and select "Generate Variant of AF3 Project"
- Select any Alternative for the AlternativeFeature (make sure to click to an empty table cell after selection)
- Select "None" again for the AlternativeFeature (make sure to click to an empty table cell after selection)
- Observe: There is no exception and the configuration can still be edited
