Hi,

in your gmfgraph model you can define labels to which you can map your expression labels. Do you run into this (https://bugs.eclipse.org/bugs/show_bug.cgi?id=331875)?

Hi,

I solve this problem by fixing the generated genmodel with a qvto transformation that is executed each time the genmodel is produced. Do the following:

1) create a folder called transformation
2) create a file called postRec.qvto in this folder
3) place the following code in it


modeltype GMFGEN uses gmfgen('http://www.eclipse.org/gmf/2009/GenModel');
	
transformation postRec(inout gmfgenModel : GMFGEN);
	
 
main() {
--fix BUG 331875
	gmfgenModel.objectsOfType(ExpressionLabelParser)->forEach(parser)
	{
		parser.className := parser.className.concat(parser._uses->first().container().oclAsType(GenCommonBase).visualID.toString());
	};
}

4) On the last page of the genmodel generation wizard select "Extra in-place gmfgen transformation after a reconcile step"
5) Fill into the text box platform:/resource/pluginname/transformation/filename.qvto
6) Press finish

This should solve the problem if you run into this bug.
