    <p>I had been trying for ages to generalize this kind of process, but in my case I was only concerned with the order of first event listener in the chain. </p> <p>If it's of any use, here is my jQuery plugin that binds an event listener that is always triggered before any others:</p> <p>** <em>UPDATED inline with jQuery changes (thanks Toskan)</em> **</p> <pre><code>(function($) { $.fn.bindFirst = function(/*String*/ eventType, /*[Object])*/ eventData, /*Function*/ handler) { var indexOfDot = eventType.indexOf("."); var eventNameSpace = indexOfDot &gt; 0 ? eventType.substring(indexOfDot) : ""; eventType = indexOfDot &gt; 0 ? eventType.substring(0, indexOfDot) : eventType; handler = handler == undefined ? eventData : handler; eventData = typeof eventData == "function" ? {} : eventData; return this.each(function() { var $this = $(this); var currentAttrListener = this["on" + eventType]; if (currentAttrListener) { $this.bind(eventType, function(e) { return currentAttrListener(e.originalEvent); }); this["on" + eventType] = null; } $this.bind(eventType + eventNameSpace, eventData, handler); var allEvents = $this.data("events") || $._data($this[0], "events"); var typeEvents = allEvents[eventType]; var newEvent = typeEvents.pop(); typeEvents.unshift(newEvent); }); }; })(jQuery); </code></pre> <p><strong>Things to note:</strong></p> <ul> <li>This hasn't been fully tested.</li> <li>It relies on the internals of the jQuery framework not changing (only tested with 1.5.2).</li> <li>It will not necessarily get triggered before event listeners that are bound in any way other than as an attribute of the source element or using jQuery bind() and other associated functions.</li> </ul>

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.

SQuiL has stopped working due to an internal error.

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