    <p>I'm not sure exactly where this is happening, but what I'm trying to do is make a scrolling ticker using flex, and it works fine when there is one of them on the screen, but when there are two, strange things happen. </p> <p>The way I have designed this for live updating, when the child of my hbox goes off the screen, I remove it and add another child to the end of it. This happens to reset the X position of the hbox, which isn't too bad, but it also resets the X position of any other hbox I have on the screen. Here is code that demonstrates what I'm seeing:</p> <p>To use this, run the flex program, then click in the first hbox to set its x position to your mouseX. When the x position of the second hbox (hbox3) is reset, so will the first hbox's (hbox2) X position.</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;mx:Application creationComplete="addToBoxes()" xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical" &gt; &lt;mx:Script&gt; &lt;![CDATA[ import mx.controls.Button; private const speed:Number = 1; private function moveBox3():void{ box3.move(box3.x + speed, box3.y) if(Math.random() &gt; .99 &amp;&amp; box3.numChildren &gt; 0) box3.removeChildAt(0) callLater(moveBox3) } private function addToBoxes():void{ for(var i:int = 0; i &lt; 8; i++){ var a:Button = new Button; box2.addChild(a); a.label = "Box2:" + String(i) } for(var j:int = 0; j &lt; 8; j++){ var b:Button = new Button; box3.addChild(b) b.label = "Box3: " + String(j) } } ]]&gt; &lt;/mx:Script&gt; &lt;mx:HBox id="box2" width="100%" click="box2.x = mouseX" borderStyle="solid"/&gt; &lt;mx:HBox id="box3" width="100%" creationComplete="moveBox3()" borderStyle="solid"/&gt; &lt;/mx:Application&gt; </code></pre> <p>How can I prevent this from happening, or what is a better way to make an updating ticker like I am trying to do?</p>

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.
