Hi,

In Galileo, I want to use «targetDef.proceed()» to "call" the parent rule to proceed with the transformation, but I get an error when do the transformation:

Exception (Can't evaluate expression: retured value is OclInvalid:in aspects::xpt::diagram::commands::CreateNodeCommand, line 23) while generating code
Can't evaluate expression: retured value is OclInvalid:in aspects::xpt::diagram::commands::CreateNodeCommand, line 23

My template code is:

«AROUND CreateNodeCommand FOR gmfgen::GenNode-»
«EXPAND xpt::Common::copyright FOR getDiagram().editorGen-»
package «getDiagram().editCommandsPackageName»;

«EXPAND xpt::Common::generatedClassComment»
public class «createCommandClassName» extends org.eclipse.gmf.runtime.emf.type.core.commands.EditElementCommand {
	«targetDef.proceed()»

	«EXPAND getEClassToEdit-»
	
	...
}
«ENDAROUND»

Could anybody help me please?
Thanks!!

Marc

Hello Marc,

are you using GMF's Xpand (fork?). Search the weg for the error message you posted resulted in org.eclipse.gmf.internal.xpand.ocl.ExpressionHelper. If so this should be a question asked in the GMF forum.
