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,

The problem is that the cars defined in Car.xmi are instances from the
object Car of Old.ecore which is different from Car of New.xmi. (type
problem)

To complete your transformation, you need to add a rule transforming
cars from Old.ecore to cars from New.ecore.

rule oldCar2newCar {
from oc : Old!Car
to nc : New!Car (
type <- oc.type
)
}

Hi,

When I run the first time the transformation, it works fine. When I try to
launch it the second time, it throws me the same exception. If I close
Eclipse and re-open it, then the first time it works.

My problem is that I have a more complex transformation, and when I apply
the rule for elements with references to another model file, it throws me
the same exception.

Could you please tell me if you get this exception?

Hi,

No, I do not manage to get your exception...
concerning your issue:
when dealing with inter-referencing models, you have to make mention of
all of them in the transformation header:

create OUT : New from IN : Old, IN2 : Old;

Then, at launch config time, indicate that IN is Old.xmi and IN2 is Car.xmi.

This is working for me.

Quentin

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 !)

Quentin GLINEUR
