I was not calling super.init(). This was my problem. Thanks to all for the help!

From: Billie Rinaldi [mailto:[email protected]] Sent: Friday, February 28, 2014 9:58 AM To: [email protected] Subject: Re: Null source for iterator You probably don't want to call deepCopy during init. Also, if your CustomFilter extends WrappingIterator, the above implementation of deepCopy will not help because WrappingIterator.deepCopy throws UnsupportedOperationException. So maybe that's not the problem, anyway. Are you calling super.init at the beginning of your init method?

Inside the deepCopy method you will need to make sure you copy any options your iterator implements.
