Hi, I have a problem with an object that has a Space in it's ID Name. The object causes several problems because it sometimes cannot be found. The object is contained in a catalog_aware class and cannot be renamed or deleted because an error occurs: Error Type: ValueError Error Value: Uncatalog of absent id 'Album/Narrentreffen2000/Fete%201' Anyone has a clue how I can get rid of such an object?
