rules transformation problem [message #1689582]

Hello everybody,

I'm working on some issues I'm meeting trying to make transformation rules from MetaSysml to MetaAcme.

Here are 2 very simple rules:

rule Bddiagram2Family {
	from  fam: MetaSysml!BDDiagram
	to  
	     t : MetaAcme!Family (  name        <- fam.name
)}

rule   Bddiagram2System {
	from sys: MetaSysml!BDDiagram 
	to  
	     t : MetaAcme!System ( 
		  name     <- 'System' ,
		 family   <- s.extend
)}

The problem is that I get this error when executed:

org.eclipse.m2m.atl.engine.emfvm.VMException: Trying to register several rules as default for element org.eclipse.emf.ecore.impl.DynamicEObjectImpl@9fff91 (eClass: org.eclipse.emf.ecore.impl.EClassImpl@68160c (name: BDDiagram) (instanceClassName: null) (abstract: false, interface: false)) : Bddiagram2Family and Bddiagram2System

Do I need to modify the metamodel? or maybe some other solutions exists...

Thank you very much.

replace

}

rule   Bddiagram2System {
	from sys: MetaSysml!BDDiagram 
	to

by a comma and you're good to go.
As the message says, an element can only be matched by one rule only but a rule can produce multiple outputs.
