    <p>Here's the simplified code:</p> <pre><code>&lt;html&gt; &lt;head&gt; &lt;script type="text/javascript"&gt; var ParentDiv = new Class ({ initialize : function(htmlElement) { console.log('debug: parent object created'); $$('.childDiv').each(function(childDiv){ childDiv = new ChildDiv(childDiv); }) htmlElement.addEvents({ 'click': function (){ console.log('debug: clicked parent'); }, 'testEvent' : function(){ console.log('debug: complex logic altering inner HTML of the element'); } }) } }); function initParent () { $$('.parentDiv').each(function(parentDiv){parentDiv = new ParentDiv(parentDiv);}) } var ChildDiv = new Class ({ initialize : function(htmlElement) { console.log('debug: child object created'); htmlElement.addEvent('click', function (){ console.log('debug: clicked child'); this.addEvent('testEvent', function(){console.log('debug: grabbed an event in child element, fired by child element')}) this.fireEvent('testEvent'); }) } }); document.addEvent('domready', function(){ initParent(); }); &lt;/script&gt; &lt;/head&gt; &lt;body&gt; &lt;div class="parentDiv"&gt; &lt;div&gt; &lt;div&gt; &lt;div&gt; &lt;div class="childDiv"&gt;Clicky Thingy&lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>The outcome is the following: neither of the events are grabbed by parent object's event listeners, while capturing the events is something I'm trying to achieve. A possible occurance of such structure: we have a bunch of control elements on the page, they all fire their own events, while the document or any other kind of container manipulates the content within based on the captured event's type.</p> <p>So, is there a way to make 'debug: complex logic altering inner HTML of the element' appear in the console box with the use of custom events?</p>

    1. COI would register only one click listener for the whole document. once fired you can traverse the dom upwards beginning at the target element. You can test if the current element has a »childDiv« or »parentDiv« class to filter out your desired html elements.

    2. CO`htmlElement.addEvent('click', function (){` -> `this` === `htmlElement` - not your instance. you need to bind it or pass a reference to bubble the event to the instance. as it stands, you are firing an event on the dom element itself.

    3. CO@philipp the `click` event was added just for the ease of debug, while, as I've described, my problem is to make custom events work, when the custom event is fired by an element within one object and captured by an element within another object

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.
