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

                 Key: RF-4792
                 URL: https://jira.jboss.org/jira/browse/RF-4792
             Project: RichFaces
          Issue Type: Bug
    Affects Versions: 3.2.2
         Environment: Rich:orderingList throws null pointer exception while we drop some item in it, when empty
            Reporter: Nik Raut
            Priority: Critical


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:
