On the demo page:

http://www.trirand.com/blog/ph.....efault.php

if you scroll all the way down on the grid and then start scrolling up with the mouse wheel, the pages are not loaded corectly.

There are multiple ajax calls to load the previous page, where it should probably be only one.

I am not sure if it happens every time but it happens only with the mouse wheel scrolling.

So you can see from the OrderIDs that pages are repeated.

This seems to me as a serious bug and if somenone knows a workaround I would greatly appreciate it.

Note that this does not happen on scroll down, only on scroll up.

I don't understand why nobody is replying, even if it is just to confirm that this is a known bug

I've experienced the very same bug your're reporting. I observe that the browser performs two requests for the same page number, and puts the result of both of these requests into the grid. The result is that the grid now contains duplicate rows with the same ids.

In my opinion this is a serious bug which should be fixed as soon as possible. We're using jqGrid in the project I'm working on and this problem is really giving us a headache.

I noticed this problem as well. It's always with the last page requested.

..And it is happening only on scroll up. Still no luck with this issue. Please someone from the dev team, just aknowledge that this is something that needs to be fixed. I am not asking for a fix, I am asking for an answer! Two months has passed and no feedback. Please!

Thank you Tony. Any idea for a workaround? I have been studying the code since there is no way I can replace jqgrid with anything else right now (deep into development phase). I don't know how to deal with it but if there is a general idea for a fix maybe I can try and work on it.

Thanks
