WHAT I WANT TO DO
I have two model files My.amodel and My.bmodel
My.bmodel contains references to My.amodel
Now I want to use ATL to create a copy from My.bmodel to My_out.bmodel
Preserving the references to My.amodel
THE PROBLEM
This works as long as I just copy the elements in My.bmodel without the
refs to My.amodel.
As soon as I try to set the references to the corresponding elements in
My.amodel the transformation fails with a java.lang.ClassCastException.
See the problematic line at ##### in the ATL file below.
Thanks for any hints,
Goetz
See attachment with zip of project.
--------- ADDITIONAL INFOS ---------
I assume that the problem comes from the fact that ATL tries to handle
elements in My.amodel and for some reason it has wrong information about
the meta-model and the classes in it. Hence, it tries to do a cast.
Whereas I would expect it to leave My.amodel untouched.
Could something be wrong with the "registration" or identification of
EMF/Ecore meta models (with Namespace/URI) . Could I check something
about that? I noticed that, despite the launch configuration, the
transformation will only execute of the .ecore files are in certain
folders in the workspace.
--------- copyBModelWithRefs.atl ---------
module copyBModelWithoutRefs; -- Module Template

from s : BMETA!BModel
to t : BMETA!BModel mapsTo s (

elements <- s.elements
)
}
rule BElement {

name <- s.name.debug('BElement'),
-- ##### THIS IS THE PROBLEMATIC LINE #####

So you don't want to recreate a My_out.amodel ? I ask because that's the
case in your transformation sample.

I tried your sample but the metamodel B didn't validate because the
reference to AElements was incorrectly set.
Here is your file :
<eStructuralFeatures xsi:type="ecore:EReference"
name="correspondingAElement"
ordered="false" eType="ecore:EClass
.../../org.example.amodel/model/amodel.ecore#//AElement"/>
And the value I corrected :
<eStructuralFeatures xsi:type="ecore:EReference"
name="correspondingAElement"
ordered="false" eType="ecore:EClass amodel.ecore#//AElement"/>

If you don't want to copy AMETA elements, you don't need to refer to the
ain/aout models.
Just do :
create bout : BMETA from bin : BMETA;
When there is a reference between two input models, the metamodel
reference is implicit, and the two models are loaded.

Notice that the mapsTo instruction belongs to ATL syntax but has no
effects for now.

Finally, you need to know that the loading of referenced metamodel has
been corrected recently. So check you use the last ATL version.
Best regards,
William
