Why doesn't the generated editor use it?
I couldn't find any trace of info about it apart the
ext.point description, but it seems inconsistent to me.
So I put together the following snippets myself:
<extension
point="org.eclipse.gmf.runtime.common.ui.services.editorProviders ">
<EditorProvider
class="exp.diagram.custom.providers.MyLEditorProvider">
<Priority name="Highest"/>
<Policy class="exp.diagram.custom.providers.MyEditorProvider"/>
</EditorProvider>
</extension>
import org.eclipse.gmf.runtime.common.core.service.IProviderPolicy;
import
org.eclipse.gmf.runtime.common.ui.services.editor.AbstractEd itorProvider;
public class MyEditorProvider extends AbstractEditorProvider implements
IProviderPolicy {
.... and so on...
}
Unfortunately none of the methods of AbstractEditorProvider and / or
IProviderPolicy
ever gets called !?
Any comment from somebody more experienced than me?

Hi,
I'm having the same problem: I registered an EditorProvider (exactly as
Vlad did), but the provider would never be called. I've overwritten the
provider's constructor and set a breakpoint, but it's not even instantiated.
What am I doing wrong? Do I have to provide a policy (Vlad didn't)? Are
there any examples on how to use this extension point?
Thanks,
Chris
