Home » Modeling » Compare » Resolving Proxies(How do I force proxies to resolve to allow correct comparison?)

I have an xtext based model that I'm using with EMF Compare. When comparing the two models using the UI, there are errneous reference changes. This is a result of the "changed" values being proxies. The model supports references to other files but in this particular case, the proxies are references to objects within thge same resource. The URIs for the proxies are different but the resolved objects are correctly matched by EMF Compare.

I was able to get comparisong to work as desired by resolving the relevant proxies during postMatch() in a IPostProcessor. Is there a more appropriate way to ensure these proxies are resolved and that the comparison works as expected?

Hello Philip,

EMF Compare UI will not resolve proxies by default, so the only choice is to override that behavior if your proxy URIs are distinct. You can do that either through the postMatch as you have done, or prior to the comparison through an IResourceSetHook (see extension point org.eclipse.emf.compare.ide.resourceSetHook).

Thanks, I'll take a look at that.
