Parallel requests with Ext.Ajax.request

[Ronits]

Hi,
I would like to know the mechanism to fire parallel Ajax requests in ExtJS.
Using a
$.when().then() enables the mechanism in jQuery.
Also, if any other approach is there, please suggest.

Thanks,
Ronit

They aren't parallel requests, it's basically just syntax sugar for callbacks.

But, thing is, within when(), I can put multiple ajax requests which are fired simultaneously, and the time taken would be the maximum time taken by any of the requests.
How do I handle the same in ExtJS... (without using jQuery syntax).

This feature doesn't exist in Ext JS. However, someone implemented promises/deferreds and a new Ajax singleton that uses them.

Ext.ux.Deferred (http://www.sencha.com/forum/showthread.php?264163-Ext.ux.Deferred)

I've never used these myself so I don't know if it covers your use cases, but it's a start.
