Description Vincent Richard CLA 2017-03-08 09:11:20 EST 
The only available variable at runtime in a begin operation of a diagram description is self, pointing to the semantic context of the diagram being created.

For the purpose of creating views at diagram creation time, it would be useful to make the diagram itself available in a variable.

VSM and modeling project to import to reproduce the pb

To reproduce the problem open the modeling project, right click on the EPackage and select "new 513309 auto init create view"

expected result: 
- the diagram is opened and there is a black node in it for the first EClass of the model

actual result:
- the nothing happens, the execution of the CreateView actually fails leading to a rollback of the representation creation.
