    <p>Deferreds can be resolved/rejected only once... However, I think the issue is how you're structuring your code...</p> <p>As long as you're initializing your deferred each time, there isn't any problem in doing this... I think the issue is this:</p> <blockquote> <p>First, i declare the deferred as global var:</p> <pre><code>var treatment1 =$.Deferred(); var treatment2 = $.Deferred(); </code></pre> </blockquote> <p>Instead, can you try doing this in a function that's invoked in the button click </p> <blockquote> <p>The user can clic a button to search for users</p> </blockquote> <p>so have a function like so:</p> <pre><code>function onClick() { var treatment1 =$.ajax({url: '/call1'}); var treatment2 = $.ajax({url: '/call2'}); $.when(treatment1, treatment2).done(function(obj1, obj2) { // do whatever else you need }); } </code></pre> <p>Now from the rest of your post, looks like you're trying to reuse the deferreds - but in that case, your original solution should not have a problem with keeping deffereds as global since your done will be called with whatever data they were resolved with.</p> <p>Can you post some more of your code to help explain what you're trying to do.</p> <p><strong>Updated from my own comment below for elaboration</strong></p> <p>based on op's fiddle, he wants to be able to trigger dependent action multiple times. Solution is to have the dependent action create new deferreds and hook up a <code>$.when</code> to itself. See updated fiddle at <a href="http://jsfiddle.net/PLce6/15/" rel="nofollow">http://jsfiddle.net/PLce6/15/</a></p> <pre><code>// global var d1 = $.Deferred(); var d2 = $.Deferred(); var d3 = $.Deferred(); // here's the reset function resetDeferreds() { d1 = $.Deferred(); d2 = $.Deferred(); d3 = $.Deferred(); $.when(d1, d2, d3).done( function (responseData1, responseData2, responseData3) { DoGlobalTreatmentWithAllResponseData(responseData1, responseData2, responseData3); resetDeferreds(); }); // the onclick handlers function do3() { d3.resolve('do3 '); return d3; } // the top level $.when $.when(d1, d2, d3).done(function (responseData1, responseData2, responseData3) { DoGlobalTreatmentWithAllResponseData(responseData1, responseData2, responseData3); resetDeferreds(); }); </code></pre>

    1. COthe way my code is structured, i cannot get the result directly from my ajax service as there is some tratment after the ajax call. Please see my sample code updaded at the end of my thread. Thx

    2. COThe issue is that each click event triggers it's own deferred behavior and cues a dependent response. That dependent response requires a set of deferred calls to have completed. See his example on jsfiddle. and my edit, linked above in my "answer" comment.

    3. CO@seblurtz: url to fiddle http://jsfiddle.net/PLce6/15/ it does what you wanted... Basically, once all the dependent action is taken, create a new set of deferreds and set up a new $.when on them to take the same action.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
