Fn.yiilistview.update How To Not Delete The Old List Before Ajax Complete?

I’m using fn.yiiListView.update too update my CListView. I noticed that every time this function gets triggered, it clears the old clistview first, then load, then output the new listview.

How can I make it so it does not clear the old listview until the new thing is loaded, so user won’t notice a blank listview with loader image only during this process?

Please advice, thanks.


Loader image should be overlayed during this process .This is one of the way to avoid user using empty page
