I suspect this problem is occurring because you have placed your ActionForm in request scope and have not provided "lazy initialization" capability for your indexed getters. Because you have a fairly complex structure of questions and options that would be hard to recreate, I would recommmend that you specify session scope for the ActionForm in this case.

This article will give you some more insights as to why this is happening.
