I stand corrected; I failed to spot the potential for an NPE in the auto-unboxing (though I think the NPE would occur on the preceding line, no?).It's quite legitimate to cast a null Object (which is what would be coming back from the getAttribute) to an Integer. You just get a null Integer. Though I did have to test that one...:-)

So you could be correct, though my money's still on the session reference itself being null.True, considering the quality of the questions that sometimes appear on here. It sometimes feels like a game of Mastermind.
