I'm using SharePoint 2013 on O365. I have a web part page with two Data View Web Parts on it. One of them is set to asynchronous update every 15 seconds for a picture library. The other one is to a custom list and does not have the asynchronous update set. When you load the page for the first time, the DVWP with the asynchronous update displays content, while the other one doesn't display any content, just the web part title. After 15 seconds, when the asynchronous update occurs on the first web part, the content appears for the second web part. Removing the first DVWP from the web part page fixes the second web part's delayed display issue.
I've tried to configure both web parts with various settings to get the delayed display issue resolved with no luck. I've searched the web and the Forums without any luck. Can anyone else duplicate this issue or perhaps has seen this before and knows what's causing the issue or better yet has a fix?
Thanks,
-Richard.
