Hi,

I've developed a diagram editor for my EMF model. The editor receives IFileEditorInput and loads the EMF Resource from the input file.

However, if the model file is renamed while being edited, the editor still keeps the old file.

Can you recommend how to avoid this? What is the best practice?

Best Regards,
Dinko

How is the model file renamed? In the workspace itself?

Hello Ed,

That's correct, I'm talking about the scenario, when user tries to rename the file in the workspace.

I read somewhere that there's a way to set EMF Resource URI to point to the new IFile location. Resource change notification will tell me what's added and what removed, not sure how to detect which file was file moved/renamed.

Right now I've solved the problem by registering an org.eclipse.ltk.core.refactoring.participants.RenameParticipant that closes the editor (&save if dirty) before rename.

Best Regards,
Dinko

Dinko,

Yes, by implementing
org.eclipse.core.resources.IResourceChangeListener.resourceChanged(IResourceChangeEvent)
and registering it using

ResourcesPlugin.getWorkspace().addResourceChangeListener(resourceChangeListener, IResourceChangeEvent.POST_CHANGE);

you can detect renaming of workspace resources and use that to change
the URIs of resources in the resource set and I suppose changing the
editor input if the input resource is the one that's renamed.
