    <p>You receive multiple FocusEvents, because TextArea contains a TextInput that it controls. When you Focus on the TextArea, the focus is actually given to the TextInput and you receive a focus event for the TextArea, and another for the TextInput.</p> <p>The best way to limit the number of received event is to check if the target of the event is the same that the target you actually listen.</p> <pre><code>function onFocusIn(event:FocusEvent):void{ if (event.target == event.currentTarget) { trace(event.target); // only the focus events generated by the TextArea. } } </code></pre> <p><strong>EDIT</strong> So, I got back to the code with the issue about clicks, and the actual fix is really tricky. In fact, the source of the error was a combination of various same issues.</p> <ul> <li>First : the fact that TextArea and the inner TextField both send Event at the beginning.</li> <li>Second : After the beginning, when the TextField receive focus from a click, it is blocked by the parent.</li> <li>And Third : When the focus come from out of the swf, in your case, the focus event is send two times (dunno why).</li> </ul> <p>In order to fix it correctly, I had to listen to the unknown TextField within the TextArea (instead of the TextArea itself), and keep track of the focus leaving the Stage in order to inhibit the first of the two events generated. Which gives this : </p> <pre><code>import flash.events.FocusEvent; import fl.controls.TextArea; var stageFocus:Boolean = true; var field = new TextArea(); addChild(field); var field2 = new TextArea(); field2.x = 150; addChild(field2); field.addEventListener(FocusEvent.FOCUS_IN, onFocusIn); function onFocusIn(event:FocusEvent):void{ if (event.target == event.currentTarget) { if (event.target is TextField) { if (stageFocus) { // Finally ! one event at a Time and no miss. trace(DisplayObject(event.target).parent); } else { stageFocus = true; } } } else { event.target.addEventListener(FocusEvent.FOCUS_IN, onFocusIn); field.removeEventListener(FocusEvent.FOCUS_IN, onFocusIn); } } // check if the focus leave the stage (the user clic out of the swf) stage.addEventListener(FocusEvent.FOCUS_OUT, onStageFocusOut); function onStageFocusOut(event:FocusEvent) { if (event.relatedObject == null) { stageFocus = false; } } </code></pre>

    1. COThanks. I understood that TextArea's composition of a textinput was causing 2 (3 for the first time) events, but was lost as to any logical reason why. Even worse, they don't implement a common interface that supports textual properties. I'm working on a soft keyboard so that's a pain. I had a similar solution in the works that tests for Types specifically but I like your event.target vs event.currentTarget much better.

    2. COI tested your solution and while it is an improvement, there's still some weirdness. `function onFocusIn(event:FocusEvent):void{ if(event.target == event.currentTarget){ trace(event.target); } }` The first time I click in the left field I get the trace, after selecting the other and going back I get nothing. However if I use the tab key it works each time. FocusManager is not updating who has focus or something.

    3. COHa, you're right ! It looks like TextArea have many strange behavior. It seems that (the first time excepted), the FOCUS_IN event from the TextField is not repeated by the TextArea. I have a fix, but it is still not exactly perfect. I'll edit my post once I'm done with this.

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.
