Use of refInvokeOperation [message #1809896]

I am trying to use refInvokeOperation on this :


value <- s.all->refGetValue('values').refInvokeOperation('first', Sequence{})

I first refGetValue('values') to get the values and this operation works, so I can get the list. But now when I try to invoke first on the retrieved values I get this error :

org.eclipse.m2m.atl.emftvm.util.VMException: java.lang.UnsupportedOperationException: #native!org.eclipse.emf.ecore.util.EObjectResolvingEList::first()

What's could be wrong with my code ?

I think you've come across a bug, which you may report (using the text above) at https://bugs.eclipse.org/bugs/enter_bug.cgi?product=MMT.ATL

That said, on EMFTVM your code usually doesn't need reflective API (except for invoking Java static methods). This code should work just fine:

value <- s.all.values->first()

Cheers,
Dennis
