    <p>Isn't there some way to re-write the following code, such that I don't need a gigantic switch statement with every conceivable type? Also, if I can replace the switch statement with some way to dynamically create new controls, then I can make the code smaller, more direct, and don't have to anticipate the possibility of custom control types.</p> <p>Before:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"&gt; &lt;mx:Script&gt; &lt;![CDATA[ import mx.containers.HBox; import mx.controls.Button; import mx.controls.Label; public function CreateControl(event:Event):void { var Type:String=Edit.text; var NewControl:Object; switch (Type) { case 'mx.controls::Label':NewControl=new Label();break; case 'mx.controls::Button':NewControl=new Button();break; case 'mx.containers::HBox':NewControl=new HBox();break; ... every other type, including unforeseeable custom types } this.addChild(NewControl as DisplayObject); } ]]&gt; &lt;/mx:Script&gt; &lt;mx:Label text="Control Type"/&gt; &lt;mx:TextInput id="Edit"/&gt; &lt;mx:Button label="Create" click="CreateControl(event);"/&gt; &lt;/mx:WindowedApplication&gt; </code></pre> <p>AFTER:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="vertical"&gt; &lt;mx:Script&gt; &lt;![CDATA[ import mx.containers.HBox; import mx.controls.Button; import mx.controls.Label; public function CreateControl(event:Event):void { var Type:String=Edit.text; var NewControl:Object= *???*(Type); this.addChild(NewControl as DisplayObject); } ]]&gt; &lt;/mx:Script&gt; &lt;mx:Label text="Control Type"/&gt; &lt;mx:TextInput id="Edit"/&gt; &lt;mx:Button label="Create" click="CreateControl(event);"/&gt; &lt;/mx:WindowedApplication&gt; </code></pre>

    1. COSeems this is a derivative of http://stackoverflow.com/questions/3001499/dynamically-casting-in-actionscript problem I will check back when a solution to your casting has been found. But most likely you will have to put the switch statement somewhere else maybe put in another Class if you want better readability of your code. cheers :D

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.
