Oh, I'm glad to be back to Wicket. I've been off on a Struts project
for several months, and am so happy to be using simple Wicket again!
But I'm having a problem with my brain. This should be easy to figure
out, but I keep getting stuck. Maybe it's the late nights... I'm trying
to add a drop-down list, something I've done plenty often. And it ain't
working! I've got a simple test case. Code is below.
Any suggestions (including one for more coffee) would be much appreciated.
Thanks,
-- Scott
