Hi marcos,

I want to do transformation from ecore to ecore.

when i generate Hot transformation i'm getting my ATL file like this

module T_In2Out;
create PdmModelModel : PdmModel from LdmMetaModelModel : LdmMetaModel;

rule LDMModel_2_PDMModel2 {
from
v_left : LdmMetaModel!LDMModel
to
v_right : LdmMetaModel!PDMModel (
coreModel <- v_left.coreModel
)
}

but i'm expected rule is

rule LDMModel_2_PDMModel2 {
from
v_left : LdmMetaModel!LDMModel
to
v_right : PdmMetaModel!PDMModel (
coreModel <- v_left.coreModel
)
}

can u tell me in the v.right element why i'm getting
LdmMetaModel!PDMModel

instead of PdmMetaModel!PDMModel.

thanks

venky.

Hi,

it is a problem related with the identification of the model elements. The
rule is not recognizing the good metamodel.

This may occurs if you do some modifications in the metamodel in parallel:
the weaving model will have the wrong IDs. A second possibility may be
conflicting URIs/paths between the metamodels.

Regards,

Marcos.
