PostPosted: Fri Jun 30, 2006 7:57 pm    Post subject: Browser white screen with Ajax calls Reply with quote

I am using Ajax in JS to make an simple Struts call to a WebSphere application server to save a small amount of data to a database. In our development environments everything worked fine. However, we are receiving reports from users that even over fast broad band connections, they are seeing white/locked up screens in IE that lock up when making this call. I am able to recreate the white screen in both IE and Firefox in my IDE by putting alert messages in the JS and breakpoints in the Stuts action code but when I release the alert/breakpoint the screen renders OK.

We have considered refreshing the whole page to solve the problem.

Any other ideas you may have to solve this problem would be welcomed.

Thanks!
Bill

Hi Marlies or Bill,

"lock up" sounds like you're using synchronous calls to me. Does the lock go away after some time, or does the browser remain locked?

The browser was locking up.
I discovered I was making synchronous Ajax calls instead of asynchronous ones. I changed to asynchronous and it is working much better, that is, no white screen, but over the broadband connection from home the cursor displays an hour glass for a short time after the call.
Thanks for everyone's thoughts!
Bill
