Enhancement
In a TreeTableComponent, e.g. the attribute view in the administration, it is not possible to assert the selection, e.g. to use this in a scripted test.
If you try to assert the selection of a TLClass in the attribute view you get the error message that no ModelNamingScheme is available for the selected DefaultTreeTableNode.
