Can someone help me understand where the error is? I don't understand how to
read the errors that the debugger outputs.

TypeError: Error #1034: Type Coercion failed: cannot convert
mx.controls::Text@2f07ccf1 to mx.core.Container.

If you run in debug mode instead of just the regular run mode, it will give
you line numbers. But it looked like you tried to call a method on a text
control that only exists on a container, or you passed a text control as an
argument to something that needs a container.

Usually this happens when you try to change the view of a ViewStack, such as:

var myText:Text = new Text();
...
myText.text = "productCatalog";
...
myViewStack.selectedChild = myText;

The ViewStack wants a container for selectedChild, but you are passing a Text
object. It doesn't matter that the value of the Text object text property
(productCatalog) might be the same as the name of a container object within the
ViewStack.

The following code illustrates the problem, with a slightly different error,
and provides one solution:



<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
creationComplete="init()">
<mx:Script>
<![CDATA[
import mx.controls.Text;

private var myText:Text = new Text();

private function init():void{
myText.text = "view3";
}

private function clickHandler():void{
// Uncomment this line and comment out the line
// after that to see the error:
//myViewStack.selectedChild = myText.text;
myViewStack.selectedChild = this[myText.text];
}
]]>
</mx:Script>
<mx:LinkBar dataProvider="{myViewStack}"/>
<mx:ViewStack id="myViewStack">
<mx:VBox id="view1" label="View1">
<mx:Label text="View 1" fontSize="20"/>
</mx:VBox>
<mx:VBox id="view2" label="View2">
<mx:Label text="View 2" fontSize="20"/>
</mx:VBox>
<mx:VBox id="view3" label="View3">
<mx:Label text="View 3" fontSize="20"/>
</mx:VBox>
</mx:ViewStack>
<mx:Button label="Select View 3"
fontSize="15" click="clickHandler()"/>
</mx:Application>
