EMF Compare with model fragments [message #117721]

Hello,

I'm having a problem trying to compare models that have fragments.
MatchService doesn't match the elements in the fragments.

To illustrate the problem I created a very simple model (3 classes) and
extracted one class into a fragment (an *.efx file). Then I created exact
copies of the model file and the fragment file.
When I compare these two models, MatchService is not able to match the
single class that is in the fragment.
DiffModel "reports" a model element (the class in the fragment) added to
one model and removed from the other model.
There are other diffs (a lot), but I don't even understand what they mean.

I have a small project with these models and a test class that does the
comparison, but it doesn't look like I can send an attachment via this
forum.
Let me know if you'd like me to send it and how I can do it.

We are using an older version of EMF compare (0.7) due to older version of
RSM we are stuck with at the moment, but there is a chance we'll be able
to upgrade soon.

Hi Renata,
first of all, thanks for your feedback :)

Correct me if I'm wrong, you have this issue with the 0.7 builds of EMF
Compare, right ?

You can track a bug using bugzilla and add your projects and example models
there : https://bugs.eclipse.org/bugs/enter_bug.cgi?product=EMFT

I hope you'll be able to upgrade your RSM version, many bugs like that are
fixed in the 0.7.0 branch. If you can't upgrade be aware that backporting
the 0.8.0 version for older Eclipse/EMF versions can be considered.

Cédric

Please
