Ok. I do not have experience with Modal windows in wicket, but do you
actually repaint the original page to even reflect the changes?
If you repaint it, and your model loads the data from DB, and the data
still does not show the changes (try to use breakpoints and debugger
to confirm this), you might have a problem with committing the changes
to your DB.
