[news.eclipse.modeling.m2m] [ATL] Multiple source patterns
Dear all,
I'm trying to write an ATL transformation in which I have two source models (from different metamodels). The code I'm using is the following:

module ControlSystemGenDSMLTransformation; -- Module Template
create dvmCOOPN : COOPNMetaModel from dvm : GenericCospel, cfc : COOPNMetaModel;

rule init {
	
	from
		system : GenericCospel!System
	to
		coopnpackage: COOPNMetaModel!COOPNPackage(
			name <- system.name,	
			ownedModules <- system.ownedTypes
		)
}

rule ruleType {
	from
		t : GenericCospel!Type,
		c : COOPNMetaModel!COOPNPackage(c.name= 'cfc')

	to
		....
		....
}

If I comment the line "c : COOPNMetaModel!COOPNPackage(c.name= 'cfc')" everything works fine otherwise I've the following errors:
