I tried this.

I created a custom popup menu which launch :
a CustomExecuteTemplatesAction extends ExecuteTemplatesAction, overriden 
the createOperation Method by return CustomExecuteTemplatesOperation
CustomExecuteTemplatesOperation extends ExecuteTemplatesOperation, 
overriden the createGenerator which return a CustomGenerator
CustomGenerator extends Generator, here I'm calling the dogenerateClass

I tried with argument :
        doGenerateJavaClass(

myEmittersCustom.getPropertySourceEmitter()/*newXpandEmitter("xpt::propsheet::PropertySource::Class")*/,
                "org.ow2.jasmine.design.model.jonas.diagram.sheet",
                "PropertySourceExtended",
                myDiagram);
	}

This exception is thrown by Eclipse while generating :
Problems while generating code

It may be other thing to do but what? Do I declare the path to the 
template? isn't already declare in the XPandEmitter constructor?
