Scroller with custom additional data

jd0000

I'm using the Scrolller extension, and I also have some additional custom filter elements i've added. I use ajax.data to get the value of the custom filters to send to my server. On the first (and for some reason, second) draw, it looks like the ajax.data function gets called. But as I continue to scroll down, it stops using the ajax.data function so my custom filters are no longer sent. Is there somewhere else I need to set the custom ajax.data function for Scroller to use it?

So I realized I was using an older version of Scroller (1.2.0). I think it may be fixed in later version. However, now that I've tried both 1.2.1 and 1.2.2-dev, it doesnt work at all - it is always sending NaN as the length. Anyone have any ideas on a fix or what I may be doing wrong?
