[ATL] references between in and out models [message #78856]

Hi,

my problem is:

I have 2 metamodels (catalogMM and configurationMM) and I want to
transform a model of first one to the second one. Problem is that I have a
reference in second metamodel to an object of first one:

CatalogMM has an element Catalog.
ConfigurationMM has an element Configuration which has a reference
(catalog) to the element Catalog of CatalogMM.

The transformation between elements could be like this:

rule Catalog2Configuration {
from
i : CATALOG!Catalog
to
o : CONFIGURATION!Configuration (
name <- 'Transformation UML2DB',
catalog <- i
)
}

It transforms without problems but when I open out model, the reference
hasn't value.
I have done 2 models as example and I have realized that this reference is
represented with href that contains a ref to the first model.

How can I solve this ?¿

Thanks.

First you need to switch allowInterModelReferences on.
Also if you have a rule transforming A -> B, and you want to set B.a to
A you need to do this in the imperative part of your rule, because the
engine will know that it has transform A to B and will set B.a to B.

do{
