Hi,
I have an old metamodel (Old.ecore) and a new one (New.ecore).
I have two model files (OldM.xmi and Car.xmi) . The first one contains a
reference to the second one. I want to transform the Old.xmi to New.xmi
and keep the reference to Car.xmi. When I run the transformation,
I get the following exception:

Hi,
Thank you for your response.
If I add 'Car.xmi' as a source model for my transformation, then due to
the rule 'oldCar2newCar', the elements of 'Car.xmi' will be copied to my
new model file 'New.xmi'. And I do not
want this to happen because I have to keep the external references to the
elements of the file 'Car.xmi'.
If I remove 'Car.xmi' from the source models, I get the same exception.
Unfortunately I still haven't found a solution for my problem and I am
blocked.
Regards,
Anca

Hi,
OK, if what you REALLY want is new.xmi to have references to car.xmi
(which, to me, breaks the conformance of new.xmi to new.ecore because
you assign Old!Car in place of New!Car)
then the transformation is:
module Old2New; -- Module Template
create OUT : New from IN : Old, IN2 : Old;
rule Old2New {
from s:Old!Person
to t:New!Person (
fullName <- s.name,
Car <- Sequence {s.Car}
)
}
(It works !)
