Dear all

I need to duplicate outgoing transitions of a composite state for each simple state inside it.
After some tries, I have to use a distinct/foreach block (I can't use lazy block for this part)...
For copying triggers of theses transitions, I use a Lazy rule (see below trigger <- outTrans.trigger->collect(tr | thisModule.Trigger(tr)) )....

the problem is : the statement given above returns a Sequence of Triggers (thats what I wanted), but, in the target model, only one trigger appears belonging to the transition... the others are attached to the root of the model...

Somebody know what do I miss ?
Is there a problem calling a lazy rule inside a distinct block ?

Thanks for your help
Kind regards
Cedric

lazy rule Trigger {
    from s : UML!"uml::Trigger" 
    to t : UML!"uml::Trigger" (
        name <- s.name,
        visibility <- s.visibility,
        eAnnotations <- s.eAnnotations,
        ownedComment <- s.ownedComment,
        clientDependency <- s.clientDependency,
        nameExpression <- s.nameExpression,
        event <- s.event,
        port <- s.port)
}


rule StateSimpleInsideLeaf extends State {
    from s : UML!State (Condition[...])
    to t : UML!State (
    	name <- s.name,
    	outgoing <- s.outgoing->union(outgoingLeafTransition)->flatten()->excluding(OclUndefined)
		
    ),
	outgoingLeafTransition : distinct UML!Transition foreach(outTrans in s.getContainingLeafState().outgoing)(
		name <- (outTrans.name + '_from' + s.name),
		target <- outTrans.target,
		source <- s,
        trigger <- outTrans.trigger->collect(tr | thisModule.Trigger(tr))					               
								   
	)
}
