Indexer error

[S. M. Mousavi Jahan Abadi]

Hi guys,   When I try to addIndexer to a collection, I get NullPointerException (stack trace is attached to end of this letter). As I have searched in users mailing list, same report was reported about 1 year ago, and Tom Bradford has mentioned he will fix this bug within one day. But I couldn’t find any following information. So, can somebody please help me to solve this bug, and give me a reference to fix patch? Thank you in advance.   Best regards,   S. M. Mousavi Jahan Abadi @ Digital Dream, Inc.
