Wicket 6 DefaultDataTable navigation don't work in Firefox

Question

After porting from Wicket 1.5.x to 6.0.20 pages using DefaultDataTable don't work in navigation toolbar when viewed in Firefox (in Google Chrome is OK)

a) events OnClick() in java classes of Navigation Toolbar never hit b) the whole Page is constructed new (recreated) after mouse click (in Firefox)

I'm not big hacker in AJAX events (EDIT) and event routing.

Answer 1

SOLUTION: Wicket & Firefox (mostly Firefox) always had a problem when some images are missing (no matter from application Java code, html or css) Older post I have found is dated 2007

Problem is not only with DataTable but for basic Link() { public void onClick() { }
