[news.eclipse.modeling.m2m] [ATL] Operation (EObject) eGet with enumerat

["Jose E. Rivera" <rivera@xxxxxxxxxx>]

Hi all,

I'm using (EObject) eGet(EStructuralFeature) operation to get the value 
of Objects' attributes and references. In all cases it works properly, 
but I get an error when trying to get the value of an attribute that has 
a EEnumLiteral as value...

The ATL rule I'm working with is the following:

lazy rule MaudeDataType{
  from
    o : Ecore!EObject,
    a : Ecore!EAttribute,
    i : Integer
  using {...}
  to
    c : Maude!Constant(
      op <- if ...
        else if a.eType.oclIsKindOf(Ecore!EEnum)
                 then o.eGet(a)->asSequence()->at(i).name
             else o.eGet(a)->asSequence()->at(i).toString()
             endif
        endif,
      ...
    )
}

For attributes with a simple data type value works properly (the "else" 
branch), but when the value is a enumeration literal (the "then" branch) 
does not, and the following error:

GRAVE: ERROR: get unsupported on OclAny.
java.lang.RuntimeException: ERROR: get unsupported on OclAny.

at org.eclipse.m2m.atl.engine.vm.ASMOperation.exec(ASMOperation.java:161)...

is obtained. (In the example, i=1)
If (as I have been told in e.t.emf newsgroup) the generated EMF code for 
eGet (or by the dynamic instance) works correctly for enums, what can be 
the problem?

Thanks in advance,
