<p>Would really appreciate if anyone can help me figure out why I am unable to fire events programmatically when using event delegation in MooTools (from the Element.Delegation class).</p> <p>There is a parent <code><div></code> that has a <code>change</code> listener on some child <code><input></code> elements. When the change event is triggered by user actions, the handler on the parent div gets triggered, but when I fire it programmatically with <code>fireEvent</code> on any child input, nothing happens. The basic setup is:</p> <h3>html</h3> <pre><code><div id="listener"> <input type="text" id="color" class="color" /> </div> </code></pre> <h3>js</h3> <pre><code>$("listener").addEvent("change:relay(.color)", function() { alert("changed!!"); }); $("color").fireEvent("change"); // nothing happens </code></pre> <p>The event handler on the parent div does not get called. Any help is appreciated. Cheers!</p> <hr /> <p>Related question: Do events triggered with <code>fireEvent</code> bubble at all in the DOM tree? My current hack is to dispatch the event natively which is working (but a hack nonetheless) - <a href="http://jsfiddle.net/SZZ3Z/1/" rel="noreferrer">http://jsfiddle.net/SZZ3Z/1/</a></p> <pre><code>var event = document.createEvent("HTMLEvents") event.initEvent("change", true); document.getElementById("color").dispatchEvent(event); // instead of fireEvent </code></pre>

Guidance

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.
