The first time the page is render the dropdownchoices works fine. I took the
example from the wicket examples.
The problem is after the submit. When I submit the form and the page is
render again the data of the dataview is filtered ok but the dropdownchoices
aren't working and there is no ajax scripts in the html.
Thanks !!
Pablo.
