Hi all,

I'm still busy with copying one metamodel to another metamodel (with the Ecore model as meta-metamodel). I now get a weird error while copying EEnumLiterals's. My code is as follows:

rule copyEEnumLiteralLib{
	from
		a : MM1!EEnumLiteral
	to
		p : MM2!EEnumLiteral(
			eAnnotations <- a.eAnnotations,
			instance <- a.instance,
			literal <- a.literal,
			name <- a.name,
			value <- a.value
		)
}

where both MM1 and MM2 are the ecore metamodel (platform:/plugin/org.eclipse.emf.ecore/model/Ecore.ecore). No fancy code, I just copy everything from one model to another.

I now get the following error:

org.eclipse.m2m.atl.engine.emfvm.VMException: org.eclipse.m2m.atl.engine.emfvm.lib.EnumLiteral cannot be cast to org.eclipse.emf.common.util.Enumerator
	at __applycopyEEnumLiteralLib(merge.atl[446:4-446:26])
		local variables: self=thisModule, link=org.eclipse.m2m.atl.engine.emfvm.lib.TransientLink@4daf4a, a=Library!I:MM1!EEnumLiteral, p=InstMM!<unnamed>:MM1!EEnumLiteral
	at __exec__(merge.atl)
		local variables: self=thisModule, e=org.eclipse.m2m.atl.engine.emfvm.lib.TransientLink@4daf4a
	at main(merge.atl)
		local variables: self=thisModule

does anyone have any idea where this comes from?

Thanks already,
