Bug 129467 [implementation] CompilationUnitDocumentProvider#createFakeCompiltationUnit should check for null path
Reported: 2006-02-25 18:00:13 | Status: resolved fixed

Version: 3.2.0 Build id: I20060217-1115 The annotate view in subclipse was broken by the addition of fake working copies in the comilation unit editor. Our implementation of IStorage#getFullPath was always returning null (as is allowed by the spec). Would it be possible to update CompilationUnitDocumentProvider#createFakeCompiltationUnit to return null if the full path of the IStorage is null? We are also going to update our IStorage implementation to return a valid path to take advantage of the fake working copies. org.eclipse.jface.text.Assert$AssertionFailedException: null argument; at
