Description Ed Willink CLA 2011-10-19 12:45:13 EDT 
When the GenModel editor open a genmodel it initializes it so that any drift between *.ecore edits are propagated into the genmodel.

GenModelHelper omits this stage and so the new Xtext Serializer crashes with e.g.

Hi,

I'm experiencing the same problem while generating an XText editor with a mwe2 script. Is there any advance in the processing of this bug ? Any workaround ?

The bug is no more present in Juno Release, Build id: 20120620-1657.
By the way, I was using Indigo release on MacOS.
