Hello Folks!

I am facing an UnsupportedOperationException (shown below) when doing a multiselection.
The Exception is thrown if a vertex and an edge is selected.
Selecting only nodes will not lead to an exception while selecting only edges will result in the same UnsupportedOperationException.
I've trieed to add an implementation of an ISelectionChangedListener to the Viewer without any positive result.

I would be glad if you can support me in fixing that issue.
