Yeah, I understand what you were saying now...I was just a little
burnt out last night. Thankfully there's only a link and two labels,
not a big deal to just add them w/ blank values.
So, if I don't set the number of rows, will it expand dynamically
(automatically)??

yeah, thats the advantage of using panels or fragments - a single top level
element, so in populate empty item you just stick an empty panel.
anyways, glad to hear you got it working.

Igor, I got this all working correctly now, I was just missing one of
the controls in the populateEmptyItem method. When we were going back
and forth yesterday it didn't dawn on me immediately that the entire
hierarchy of components had to be re-created in this method.
I've now got it exactly where I want it (once I make the # of rows dynamic).
Thanks for your help!
