    <p>My button handler gets called twice - once for mousedown/touchstart and a second time for mouseup/touchend.</p> <p>This happens both on my iPhone device and in my Chrome Browser.</p> <p>Using ST 1.1</p> <p>I haven't found any references to this problem which seems to suggest that something in my env is wrong, but I'm running out of things to check ...</p> <p>Examining the event objects passed to the handler in Chrome DevTools I can see that they're both simulated "tap" events, the first originating from "mousedown" and the second from "mouseup".</p> <p>Any ideas ?</p> <p><strong>EDIT:</strong></p> <p>I've found out that this happens when I add a call (even with an empty handler) to <code>Ext.EventManager.onDocumentReady</code>.</p> <p>If I remove this call, I only get clicks on "mouseup" as expected.</p> <p>If I replace it with <code>Ext.onReady</code> it works !!! This is really bewildering since one is an alias for the other ...</p> <p>code reproduction:</p> <pre><code>&lt;!DOCTYPE html&gt; &lt;html&gt; &lt;head&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=utf-8"&gt; &lt;script src="resources/Sencha/sencha-touch-debug.js" type="text/javascript"&gt;&lt;/script&gt; &lt;link href="resources/Sencha/sencha-touch.css" rel="stylesheet" type="text/css" /&gt; &lt;script type="text/javascript"&gt; MyPanel = Ext.extend(Ext.Panel, { fullscreen: true, initComponent: function() { this.items = [{ xtype: 'button', text: 'Login', handler: this.myHandler, scope: this }]; MyPanel.superclass.initComponent.apply(this, arguments); }, myHandler: function(b, e) { console.log(e.event.type); } }); Ext.EventManager.onDocumentReady(function() { }); Ext.onReady(function() { new MyPanel(); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt;&lt;/body&gt; &lt;/html&gt; </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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
