I had a similar problem. In wicket-ajax.js, I made the following changes, and
now it works fine :
if (Wicket.Focus && Wicket.Focus.lastFocusId) {
t.setRequestHeader("Wicket-FocusedElementId", Wicket.Focus.lastFocusId
|| "");
}
else {
// t.setRequestHeader("Wicket-FocusedElementId", "");
}
Hope this helps.
