[news.eclipse.modeling.gmf] Empty properties view in editor when using a ecore model with subpackages

Hello,

As mentionned in the title, I am having problems with a GMF diagram editor which is based on a ecore model with subpackages (see attached file).

Whenever I select in the editor an EditPart corresponding to a EClass of a subpackage, Its property view is always empty, this does not happen for EClass that are defined in the main (root) package.

Any idea on how to solve this issue ?

Thanks in advance,

Steven
