I think you may running into a simular problem that I ran into. I have the following scenario: page 1 has the user choose from a list of options. On page 2, the form saves the selected option of page 1 in a hidden field in its form. In addition the selected value from page 1 is used to populate a pull down on page 2. So the user hits the submit button on page 2 to save the changes and KA-BLAMMO, I get a NPE.
What was happening was the JSF was attempting to Validate the pulldown values in the Validation phase. This was before any of the hidden fields were set. So because the hidden fields weren't set, the retrieve of the pulldown was failing. I saw 1 of 2 solutions: 1) Turn off the validation of the pulldown. Because, hey... why would I need to validate a pulldown? - it isn't like a user can mistype something. OR 2) somehow get the hidden fields to be set before any retrieval of the pulldown is made. The JSF mailing list from Sun gave no help for turning off the validator for the pulldown. So I had to do the following, for which I give myself a big Capital "H" for HACK. In the contructor of the backing bean, I grabbed the request parameters myself and called the setters from there for the values that were needed to get through the validation of the pulldown. Perhaps someone here can help turn off the need to retrieve the pulldown values in the validation phase. I hope this will help your situation, as well.
