Rich:orderingList throws null pointer exception while we drop some item in it, when e

I have an orderingList with drop support. I drop an item in it from a table with drag support. It works fine when I already have some items in the orderingList but fails when empty. This feature used to work with RichFaces 3.2.0 version but after upgrading to 3.2.2.GA it starts throwing exception. The exception stack trace is below:


Exception during request processing:
