Hi

you need to execute the matching transformations according to the dependencies between them.

You can find a description in the AMW wiki.

Hi

Thanks for ur answer

Im trying to execute matching transformations in this order :

Cartesian product, Name equality, Propagation, Similarity flooding, Threshold then Link rewriting

but when i arrive at the third step (generation of propagation graph) i get an empty model (DiagramToDiagram2_cp_equal_prop.amw)

plz can u tell me what the problem may be

Can you check the execution log of Eclipse?
This can help you to discover the problem.

Btw, you need to have a couple of weaving extensions installed (mmw_match and mmw_propagation).

The extensions are explained in the following link.

Hi !

I get no messages in the execution log of eclipse when i launch a matching transformation. but the model takes too long to load when i click on.

I load, in the first wizard, (just for instance) the couple of weaving extensions : mmw_match and mmw_propagation in order to create a cartesian product.

In the second, i choose the panel (TransformationWeavingPanelExtension) and the WModel (MatchModel).

then, i choose the left and right metamodels. (to simplify, i created a slight change between the two metamodels)

i execute the cartesian product transformation, i get a model with an empty method cartesian product and other links all with sim = 0. when i try to click on, there is an error in execution log with the following messages :

Hello,

You are weaving metamodels, right? In this case, the .metadata file has a 'null' value for the models relative path. So this is not an issue.

About the error, it seems taht there is some unresolved references in your metamodel. This may be connected to the way the model elements are identified: either by XMI-IDs or by XPointer.

Marcos.
