I'm not sure what you mean by "the varStatus's index". You currently use var="bobjectList". This would be better named: var="bobject" as the var is set to each element of the table's "value" list in turn, ie refers to an element from the bobjectList, not the entire list. However the var does seem to be used ok.
The fact that this is a session-scoped bean does remove a lot of potential failures here (although session-scoped vars have lots of problems of their own). Is the bobjectList a normal ArrayList or LinkedList, or is it something special? Are you sure that it is failing on the zeroth element during postback? Maybe element zero is ok, but some other later element is failing. Adding some logging statements would again be useful here.. To be honest, if I were a gambler, I would give odds of 20:1 that this *is* a problem in your code. Though it isn't an obvious one...
