    <p>"... so the done callback is only called when all deferred are resolved, including those added later" makes no sense, however I think I know what you mean.</p> <p>If I understand correctly then you want what might be termed a "re-firable when()" - something like this (based on jQuery) :</p> <pre><code>function PromiseSet(memory, once) {//javascript Constructor var flags = []; if(memory) flags.push('memory'); if(once) flags.push('once'); var promises = [], doneCallbacks = $.Callbacks(flags.join(' ')), failCallbacks = $.Callbacks(flags.join(' ')); this.add = function(promise, val) { promises.push(promise); if(val) { this.fire(val); } return this; }; this.done = function(fn) { doneCallbacks.add(fn); return this; }; this.fail = function(fn) { failCallbacks.add(fn); return this; }; this.fire = function(val) { val = val || null; $.when.apply($, promises).then( function() { doneCallbacks.fire(val); }, function() { failCallbacks.fire(val); } ); return this; }; return this; } </code></pre> <p><em>untested</em></p> <p>All methods return this to make them chainable.</p> <p>If I've written the constructor correctly, then you can control its detailed behaviour by passing booleans to <code>new PromiseSet()</code>. For your propised usage, I think you need to pass <code>(true, false)</code>, but try other settings to see what happens.</p> <p>Sample sequence :</p> <pre><code>var myPromiseSet = new PromiseSet(true, false); myPromiseSet.add(promise1); myPromiseSet.add(promise2).add(promise3); myPromiseSet.done(myDoneFunction).fail(myFailFunction); myPromiseSet.fire("foo"); myPromiseSet.add(promise4).fire(); </code></pre>

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.
