Thank you for your input, what was happening is once the RPC was
complete the data that I was adding to the ArrayList would disappear.
So I decided to do something ugly, but it works. I am writing the data
onto a invisible div on the page then getting it then adding it to the
ArrayList. It seems to work just fine.

I am new to GWT but I am starting to get a basic understanding on how
these things work.

I was wondering if anyone knows of a way to run a function after the
RPC is complete.

Thanks!

John
