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...Is it the correct way to to access to it?
I'm working with ATL (ATLAS trasnformation language) instead of directly
with Java code, but these operations are supported as well. I get the
following error:
GRAVE: ERROR: get unsupported on OclAny.
java.lang.RuntimeException: ERROR: get unsupported on OclAny.

I saw other questions regarding this operation in this newsgroup and I
though that was the proper one. I though that implemented operations for
the Ecore metamodel were handled here,
sorry again and thank you

Jose,
Well eGet is definitely implemented by the generated EMF code or by the
dynamic instance, but I know they work correctly for enums and I don't
see anything directly EMF related on the stack, so the issue must lie
elsewhere, or in your own code, which you've not shown at all. I expect
folks will need more details from you...

Hi, Jose,
As far as I know, ATL does not use the MDT OCL implementation. I'm
afraid I won't be of much help.
Cheers,
Christian

Thank you again Ed..
Then, 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.
is obtained. (In the example, i=1)
If the generated EMF code for eGet (or by the dynamic instance) works
correctly for enums, what can be the problem?
Thanks in advance,
Jose E. Rivera
