Hi @ all,
I am currently trying to add a custom action to my gmf editor.
I added an objectContribution to the popup menu extension point.
In this the implementation class of the action is called.
After this point in the run method, i try to get the workflow file location with this piece of code:
URL url = FileLocator.toFileURL(new URL("platform:/plugin/testplugin/templates/workflowfile.mwe "));
At this point, when i want to thest the action, i get an IOException with the error code:
unable to resolve plugin "platform:/plugin/testplugin/templates/workflowfile.mwe"
I adaprted this code from the dsl-book and the cvs, so in general it should work...
If anybody knows what i am doing wrong, please help me 
any help would be apreciated.
Best regards,
Masija
The Code from the cvs mentioned above:
