Model elements view unpredictably collapses and unfolds subtrees
The model elements view collapses and unfolds subtrees for no good reason. This might have an annoying effect when modeling larger architectures.
As far as possible, the bug should be fixed in the underlying DynamicTreeContentProviderBase class. The bug also appears in other tree views (e.g., data dictionary).
Steps to reproduce (1)
- Create PlatformArchitecture
- Collapse “Hierarchic Architecture” category
- Click on PlatformArchitecture background ->“Hierarchic Architecture” category is unfolded
Steps to reproduce (2)
- Create PlatformArchitecture
- Search for “Clust” ->only “Hierarchic Architecture -> Cluster” is shown
- Delete filter
- Now the generic architecture and the RaspberryPi platforms are collapsed.
