    <p>I'm studying use <code>series.js</code>. I wrote simple example - run <code>async.series</code> for 3 functions. By curiosity I created log output before and after callback call. Unexpected for me there is no log messages 'after callback'. </p> <p>My question is - is it memory leak, and these call are still in stack and waiting to return? Or <code>async.js</code> uses special mechanism for cutting functions after callback? I tried to read <code>async.js</code> source and found nothing. </p> <p>Is there any ideas?</p> <p>Test page:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta charset="UTF-8" /&gt; &lt;title&gt;My Page&lt;/title&gt; &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js"&gt;&lt;/script&gt; &lt;script type="text/javascript" src="https://raw.github.com/caolan/async/master/lib/async.js"&gt;&lt;/script&gt; &lt;script type="text/javascript"&gt; var a = function (callback) { console.log('a before callback'); return callback(null); console.log('a after callback'); }; var b = function (callback) { console.log('b before callback'); return callback(null); console.log('b after callback'); }; var c = function (callback) { console.log('c before callback'); return callback(null); console.log('c after callback'); }; var doit = function() { console.log('click'); async.series([a, b, c, a, b, c], function(something) {console.log('async.series happy end: '+something);}); console.log('series finished'); }; $(function() { $('#bu').click(doit); }); console.log('hello'); &lt;/script&gt; &lt;/head&gt; &lt;body id="bo" class="blue"&gt; &lt;input type="button" id="bu" value="click"&gt;&lt;br /&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>Log output:</p> <pre><code>hello event.layerX and event.layerY are broken and deprecated in WebKit. They will be removed from the engine in the near future. click a before callback b before callback c before callback a before callback b before callback c before callback async.series happy end: null series finished </code></pre>

    1. CO`async` is short for asynchronous, so it makes sense that you see the messages being logged in a different order... it's not a mem-leak AFAIK

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.
