On the same repository the query:
List<CDOResourceNode> nodes = view.queryResources(null,
"", false);
works ok
It very much strikes me that this is a dup of bug 361346. Please reopen if you've updated and the problem is still there. If you can't update please check if the following code early in your app helps (and let me know): // Ensure that these 3 packages are registered with the global package registry in stand-alone EcorePackage.eINSTANCE.getClass(); EresourcePackage.eINSTANCE.getClass(); EtypesPackage.eINSTANCE.getClass(); *** This bug has been marked as a duplicate of bug 361346 *** |
