one element to multiple transformation [message #1723964]

Hello,

i have a simple transformation rules where the first class in Source has a Name and transformed to a name too in the target class. its work very well.

the thing is, i have another class which has 3 attributes + 2 associations to another classes in the source model and each association should take an attribute from another class which already been transformed.

the simple rule i wrote:

rule ResCons2Token {
	from
		D: UML!ResConsumption
	to
		Token: CPN!ResConsToken (
		
				ResCons <- D.CompName+','+D.Compunit+','+D.CPUCons+','+D.MemoryCons+','+D.PowerCons)
}

CompName + Compunit are the association names, the Ekeys for them are the attributes i need them to get from Class Components, Compunits where they already transformed for a target elements.

how can i do that? how can i use the source element to multiple transformation?

the error i got while running this transformation is:
org.eclipse.m2m.atl.engine.emfvm.VMException: Trying to register several rules as default for element org.eclipse.emf.ecore.impl.DynamicEObjectImpl@3832ea3f (eClass: org.eclipse.emf.ecore.impl.EClassImpl@3acb97b7 (name: AllocateProblem) (instanceClassName: null) (abstract: false, interface: true)) : Component2Token and CompUnit2Token

Component2Token, CompUnit2Token are the 2 rules i create before and need to get their source element in my other rule.

Thanks in Advance

It looks like you have one source element can match both of these rules, which is not allowed for the ATL matching rule in default execution mode.
