I guess that you have a Sirius project with an aird referencing a non existing viewpoint (because the file has been moved). But in that case, sirius manage it. In that case there is no error in error log and the concerned representation are not displayed in model explorer. So, Could you provide a scenario with attachment to reproduce, so that i can go further in the understanding?
Created attachment 272403 [details] Screencast about the exception
Hi Laurent! Thanks for your quick reply! The steps to reproduce the problem: 1. Check out all the source code from the Sirius repository. 2. Start Runtime Eclipse. 3. Import the 'Basic Family Sample Model' from the Sirius Examples. 4. Open the basicfamily.sample/representations.aird file 5. The Exception is thrown (see the screencast as attachment).
The Eclipse projects contained inside the /org.eclipse.sirius.tests.rcptt.properties.samples/contents/propertiestests folder in the sources should not be imported in the development workspace. They are only used in very a specific context (automated RCPTT tests). It's true they contain some inconsistencies, but those are not an issue in practice in the context they are designed for. Even without considering this particular issue, importing them in your workspace is probably not a good idea, it will contribute a lot a completely useless viewpoint definitions which are only designed for tests and will pollute the UI.
