Exception when invoking a helper method [message #915025]

Hi,

I've added a new helper method to the existing file xpt/diagram/editparts/Utils.qvto:

helper getLabelText(classbody : String, key : String) : String {

var s : String := classbody;
...

return newStr;
}

Then i call this method from a template file

«DEFINE figureText(key : String) FOR gmfgen::InnerClassViewmap»
	«getLabelText(self.classBody,key)»
«ENDDEFINE»

While generating the diagram code I get the following exception:

Problems while generating code
Exception (Cannot find operation (getLabelText(String, String)) for the type (null):in aspects::impl::diagram::editparts::NodeEditPart, line 34) while generating code

I can rule out that neither 'self.classbody' nor 'key' is null, because when I use the arguments in the template itself, everything works fine. What could be the reason for that problem?

Regards,
Rami
