null pointers

[David Wall <dw...@Yozons.com>]

I'm trying to return a fairly complex object, but I get a null pointer
exception.  From the response trace, I cannot tell if this is something I've
done, or a bug, but generally they are things I've done!  Anyway, will the
BeanSerializer correctly handle fields that are null?  These could be simple
String fields, or they could a LinkedList that hasn't been set, or a handle
to another optional object.

Thanks,
David
