Ok, problem is solved now!!!
The trick is to fill the selectItemList with ALL possible data including the matches for the result list. The framework first renders the result list and removes those matches from the SelectItemList automatically, but only if there is that object to match! So fill your SelectItemList with all possible matches and use a converter for switching from SelectItems and Strings (the pick lists) to the objects.
Hope this will help you. If not, just write a line and I will post my code here..
You forgot to post the first line which tells us about the exception type and exception message. The stacktrace is fairly worthless without that information.
