Stuff to reproduce

While trying to develop a new GMF diagram for JBI, I got the following error:

Can't evaluate LET expression: actual variable type is not assignable to declared one:in xpt::editor::DiagramEditorUtil, line 254

"
Problems while generating code

Comment 1 Mickael Istria CLA 2011-08-08 08:39:08 EDT 
This only happens when the domain model contains a DocumentRoot element (generally in case of XML/XSD-first approach for the ECore model).
Comment 2 Mickael Istria CLA 2011-08-08 09:48:04 EDT 
This issue only occurs if the top-level element of the canvas is the DocumentRoot.

Suggested patch

A suggested patch that fix the generation issue when the root of the Diagram is a DocumentRoot.
Integration tests passed OK. I'll commit it as soon as I have my diagram fully working.
