Hi,
I observed something strange in my custom editorpart, after using the emf save mechanism (strg+s). Before I use saving, everything works fine, but after saving it seems that attributes are not updated anymore, which breaks further methods. For this reason I printed out the object, which gave something interesting.
That's the object before I save, whcih is pretty fine so far:
pld.impl.VariationpointImpl@598a6f (name: Ethernetshild, description: <unset>, configStatus: Selected)
After saving, Iget the following message, which I don't really understand, but it seems to break my other functionality, as the editor don't get attributes changes anymore:
pld.impl.VariationpointImpl@c517f4 (eProxyURI: platform:/resource/test/default.pld#_1OUj8IgeEeOXj_Il_6BA_w)
Can someone tell me what the eProxyURI stuff means and why it is there?
Cheers,
Phil

Saving won't convert an object to a proxy. So do you mean you have this
problem after loading the saved model?

Hi Ed, sry for the late response.
I've set a breakpoint to handleChangedResources, but it seems that it's never really called.
My editor is extended by several tabs, which represent the model in different ways. Every tab extends EditorPart, hitting saving will call public void doSave(final IProgressMonitor progressMonitor)
Using the saving mechanism in one of the tabs give objects the eProxyURI (whatever this means).
Closing the editor and reopen it, solve this then and everything work, till I save again.
Just to clarify: When the eProxyURI is shown, it means that the model is unloaded?
If so, which methods could possibly responsible for this behaviour?
Cheers,
Phil

That's strange.

Yes.

Resource.unload, but the method that calls this in the generated editor
is handledChangedResources, which you say is never really called...

Phil,
I can't say more than I already did. Clearly you're printing out
something that indicates you have a proxy and the debug prints you added
seem to indicate that nothing has attempted to resolve that proxy or
that the proxy can't resolve...
