What about debuggint the code, this is a developers list, so if you face something you think it is a bug, you debug it and if you do not have the knowledge to debug it, you file a bug and give a pdf to test, but saying "XRef returns null when I query for it" is not enough, you don't say which code you use, you don't give a PDF, what do you expect us to do?
