----------------------------------------
Hi Guys,
Thanks for following up with this, but it's probably something we can close
out now. I've moved on to another employer and project, so I don't have
access to this code base any longer.
Thanks for your help.

> I have an ActionForm that has a getter and setter for a Collection of
