[news.eclipse.modeling.m2m] [ATL] UML stereotype problem

[unique <hr_mi@xxxxxxx>]

Hi everyone,
I make a helper to check the stereotype of a class ,the code is as
following :
--------------------------------------------------------
helper context UML!Class def: hasStereotype(stereotype : String) : Boolean =
	self.getAppliedStereotypes()->exists(e|e.name=stereotype);

-------------------------------------------------------



My code is like this :

--------------------------
module uml2bpel; -- Module Template
create OUT : BPEL from IN : UML;

rule toProcess{
	from
	    u : UML!"uml::Activity",c : UML!"uml::Class"   					
(u.oclIsTypeOf(UML!"uml::Activity") and
			c.oclIsTypeOf(UML!"uml::Class") and 						c.name='onlinesale' and
			c.hasStereotype('Process')
			)
	to
	  p : BPEL!Process(......
				)
}

-------------------------------------

I  select the UML  metamodel by URI:http://www.eclipse.org/uml2/2.0.0/UML
but it dosen't work correctly.

Anyone can help me ??

Thanks very much.
Best for wishes!
