EMF Compare problem comparing instances [message #531030] Mon, 03 May 2010 12:56 Go to next message

Hi,

I've got a problem when comparing instances with EMF Compare.
We created some dynamic instances of our meta model with the 'Create dynamic instances...' dialog of the sample ecore editor.
If I compare instances with EMF Compare, I'll always get error messages like 'The feature 'name' is not a valid feature' when expanding the tree in the top part of the compare editor.

Does EMF Compare work with dynamic instances or do I have to generate the code from the meta model? If I generate the code it works fine, but I would rather prefer to work with dynamic instances.

Could it be, that the meta model wasn't loaded correctly?


Here is the stack trace:

Does anybody have the same problem?
Is it even possible to compare instances created over the "create dynamic instance" dialog?
Do you need more information?

Hi Johannes,

Sorry, seems like I let your previous mail slip through (please use the
EMF newsgroup for EMF Compare questions).

I must confess we never tried comparing dynamic instances, and it isn't
part of our tests. Could you try with the latest version of EMF Compare
and raise a bug if it is still failing with a "feature not found" error?

My guess from the description is that there are two instances of some
Ecore model and then a dynamic instance of one is being compared against
a dynamic instance of the other. Such things should not end up
comparing as structurally equal because their Ecore models are not
identical. But this is of course just a guess based on the symptoms.

We indeed have a know bug when comparing two instances of distinct
metamodels ... I didn't understand the problem to be it in this case though.
