Hello!

I want to call a Java method placed in org.eclipse.gmf.codegen from Xpand templates. This Class is accessible because there exist an extension in the codegen plugin that allows it. I want to access to EMFUtils.

I found this entry in the news and Alex Shatalin replies with this, but I cannot get access to this Class. An error appears in the generation.

My Xpand template looks like that:

«IMPORT 'http://www.eclipse.org/gmf/2009/GenModel'»
«IMPORT 'http://www.eclipse.org/emf/2002/GenModel'»

«EXTENSION gmf::EMFUtils»

«AROUND getDiagramVisualID FOR gmfgen::GenDiagram-»
	«EXPAND xpt::Common::generatedMemberComment»
	public static void myFunction() {
		«getReferencingObjects(self)»
	}
«ENDAROUND»

And I get the following exception:
Exception (Cannot find operation (getReferencingObjects(GenContainerBase)) for the type (null):in aspects::xpt::diagram::updater::DiagramUpdater, line 26) while generating code
Cannot find operation (getReferencingObjects(GenContainerBase)) for the type (null):in aspects::xpt::diagram::updater::DiagramUpdater, line 26

What I'm doing wrong?

Thanks.
Marc

PD: Before I ask in M2T forum (link), but I think I should done here.
