I'm using the pre-Dojo-fied Tap 4 and implemented my own Ajax handler routines, so I don't know if there's a built-in Dojo hand-holding way to do this, but it's certainly possible in Tap 4. I'd imagine it's possible in 4.1 as well. In a nutshell, I created a global Ajax request object that all XMLHttp requests register with and then pass through. In the situation you described, you merely loop through your request objects and see if any have a readyState that does not equal 0 or 4 (which means it's still busy with a request). Each request object has a new parameter I added called "isInterruptable" to allow certain asynchronous requests to be overridden. To disable user interaction, you simply create a fixed DIV that's the size of the screen with a z-index greater than anything else on the page. It basically acts like a piece of glass over all the links/submit buttons/etc. They think they're clicking on a link, but are in fact clicking on this transparent DIV. Change the mouse pointer by using obj.style.cursor = "wait"; -- View this message in context: http://www.nabble.com/synchronous-ajax-tf3150705.html#a8749537 Sent from the Tapestry - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
