org.eclipse.core.commands.ExecutionException when creating Sequence Diagram [message #1745680]

Hello, I am currently developing an RCP Application that builds on Papyrus.
I have currently created my own view, that only uses Sequence Diagrams. The issue arises whenever I try to create a new papyrus model with a Sequence Diagram I get the following ERROR-message:

Any idea what causes this to happen and how it can be fixed?

The solution was quite simple when I found the correct reading material -->
http://help.eclipse.org/neon/index.jsp?topic=%2Forg.eclipse.papyrus.infra.viewpoints.doc%2Ftarget%2Fgenerated-eclipse-help%2Fviewpoints.html

You basically have to add some rules to your configuration such that the diagram specification can actually modify/create elements in the editor.

The minimal required rules can be seen at the bottom of the referenced web page above.
