Hi,

I'm running a transformation on a GMF notation file, as soon as an element is changed the file loses a lot of valuable data. The original header looks like this:
<notation:Diagram xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:ecore="http://www.eclipse.org/emf/2002/Ecore" xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.2/notation" xmlns:uml="http://www.eclipse.org/uml2/3.0.0/UML" xmi:id="_t1tkMFO5EeCshacrw33kcw" type="PapyrusUMLActivityDiagram" name="ACTIV" measurementUnit="Pixel">


And after the transformation it looks like this:
<notation:Diagram xmi:version="2.0" xmlns:xmi="http://www.omg.org/XMI" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:notation="http://www.eclipse.org/gmf/runtime/1.0.2/notation" xmi:id="_t1tkMFO5EeCshacrw33kcw" type="PapyrusUMLActivityDiagram" name="ACTIV" measurementUnit="Pixel">


So all UML and Ecore references in the model are lost. How can I stop this from happening?

I'm still looking into this problem, I can't seem to find any reason for this. The model I'm using is a Papyrus diagram notation which seems to conform to the GMF notation metamodel. In the notation metamodel the View object contains an Element object, but after running a transformation every Element object is deleted from the XML, and the header is changed as stated above.

Might the problem be that the Papyrus notation metamodel is slightly different from the GMF one (which is included in Eclipse), but still conforms to it?
