You may notice that very few questions like yours get answered on this
newsgroup. People here want to help, but our time is limited. We mostly
don't have time to try to read your code, understand what you are expecting
it to do, set up a test case for it, step through it in the debugger, try to
figure out where it is behaving differently than expected, and if it behaves
as expected for us, try to figure out what we might be doing differently
than you.
You need to do those things for yourself. Then, when you run into a
specific question like "why does method getXXX() on line YYY return null,
when I would expect it to return a ZZZ?", you will be more likely to get an
answer to that question. Especially if you explain what else you have
tried, whether the code worked in another context, and so forth.
