[news.eclipse.modeling.m2m] Re: [ATL]How to add a binding in if-else sta

[William Piers <william.piers@xxxxxxx>]

Hello,

You can try this solution (assuming that p.getName() returns a Sequence):

rule ParticipantToComponent {
  from
	p : UML!Participant
  to
	c : CLASS!Component (
		name<-p.name,
		service <- if (not p.getName().isEmpty())
				then s
				else OclUndefined
			    endif
	),
        s : CLASS!Service (
		provide<-prList
	),
      prList :distinct DS!Tprovide foreach(prName in p.getName())(
		name<-prName
	)
 }

Best regards,

William
