When creating an ExpansionRegion you can't create some nodes in it.
it seems that the error appears with use of:
- AddStructuralFeatureValueAction and AddVariableValueAction
- ReadStructuralFeatureAction and ReadVariableValueAction
- CreateObjectAction
- Central Buffer node
- BroadcastSignalAction

Reproducible: Always

Steps to Reproduce:
1.Create an ActivityDiagram
2.Create an ExpansionRegion or a StructuredActivityNode
3.Try to create a specified node in these regions
