Thanks for the quick reply.
I changed selected to initialize in setupRender, and now I'm getting the
following exception.
What's wierd about this one is that if I set a breakpoint in the
setCurrentCheckout method, it reports that selected and item are both
non-null and I can add strings to selected using the debugger, but somehow
it still throws this NullPointerException there.
