I have a GMF based plugin ad Papyrus installed in Eclipse.
If I start the GMF-plugin, its editor load correctly.
But after that, if I open a Papyrus editor, and try to drag'n'drop a shape, I can't.
The reason for that is: The GMF-plugin use org.eclipse.gmf.runtime.common.ui.services.parserProviders extension point.
As discribe here https://bugs.eclipse.org/bugs/show_bug.cgi?id=191488#c6
GMF load all declared providers, even Papyrus's provider. This make all IElementTypes to null.
To avoid this, is there a workaround?
Is it possible to not expose this extension point in Papyrus?
