I think that link did provide a solution to your original problem, 
which was that you were allocating an array of references to ItemData 
objects, but not actually creating a ItemData object.  myItemData[0] 
contained a null reference, so you got a NullPointerException when you 
tried to reference it.

I see that you have fixed the original problem.  What sort of problem 
are you having now?
