    <p>Two things:</p> <p>1) The reason your event is not firing is because you are adding the listener after you set <code>_xlist</code>.</p> <p>2) You should not be adding an event listener within your setter anyways. You should add it on the initialize or creationComplete events of your VBox component.</p> <p><strong>EDIT</strong></p> <p>Alright, after looking at your code again I can see the problem... so just a few more things.</p> <p>3) Why are you naming a method <code>init</code>, when it gets called on <code>creationComplete</code>? You should get into the habit of naming methods appropriately. For example, the method that gets called on <code>creationComplete</code> should be named: <code>onCreationComplete</code>, or <code>handleCreationComplete</code> That way, you will know what your code is doing 6 months down the road.</p> <p>4) This is your main problem: You are using the getters / setters in appropriately. If you have a setter, you should also implement a getter (unless you have a write-only field). More importantly, you should <em>use</em> the getter to access your data. In your <code>xListChanged</code> method you are not using the setter you have defined, thus nothing is getting told the <code>_xlist</code> actually changed. As such, you should change your code to:</p> <pre><code>private var _xlist:XMLListCollection; [Bindable] public function get xlist():XMLListCollection { return this._xlist; } public function set xlist(value:XMLListCollection):void { this._xlist = value; } </code></pre> <p>Whenever you want to access <code>_xlist</code>, use the GETTER. For example, change the dataProvider of your <code>List</code> component to be <code>{xlist}</code>. And the <code>xListChanged</code> method should be using the getter: <code>xlist</code> instead of directly accessing the member <code>_xlist</code>.</p>

    1. COI've moved _xlist.addEventListener(CollectionEvent.COLLECTION_CHANGE, xlistChanged); into init(event:FlexEvent) method which I call on creationComplete="init(event)" of the VBox, but this hasn't fixed my both problems. And does it make sense to call addEventListener this early, while _xlist hasn't been set by the setter method?

    3. COThanks, but I can't use GETTER/SETTER as you suggest, because it is XMLListCollection and the custom component gets an XMLList as parameter: <my:Games xlist="{games.game}"/> I've updated my question with the test code, I'm trying to use list.dataProvider.addEventListener() there... but still no luck.

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.
