wicket reads off the pagemap name off url when the page is initialized - only when there is no pagemap encoded into the url a new one is created

Thanks for the quick repsonse Igor, that appears to have been my problem.
I used the iframe because the tabular display is so wide it caused the
entire page to scroll and certain aspects of the page to be wider than I
wanted. I wrapped the data table in an iframe to give the same look as
you'd get in Swing using a JTable wrapped in a JScrollPane.
I'm a little confused as to why this fixes the problem though. In looking
at Page.getPageMap(), it initializes a new PageMap instance if the pageMap
variable is null. Wouldn't I still get a unique PageMap at that point if I
didn't send one through the constructor?
Thanks,
Allen
