Ajax Hidden DT with Scroller extention. How to init the length of the ajax post?

jean

I have a page with multiple DT on various jQueryUI tabs.
Hidden DT will show incorrect data when the tab they are in are activated, even if I call .draw() on that DT because the AJAX call pass a lenght of NaN, which is incorrect

How do I reset those var (length and other) when the tab is made visible?

Thanks!
