It's better to have a parent destroy a child than for a child to destroy
itself. It a child destroys itself, it could be in a weird state during
any code that executes after you call parent.destroyChild(this).
comp2 can call a method in comp1 like this:
click="parentDocument.deleteRow()"

Subject: [flexcoders] Re: dynamically destroy child from parent
Thanks, that makes sense. I have one problem though that I can't seem
to figure out. I am using createChild() in Comp#1 which creates
comp#2. Comp#2 includes all text inputs including a delete button. Is
it possible to have that child delete itself, or is it better to have
the parent delete the child?
If the parent is suppose to delete the child component how do you
send a reference of the child back to the parent in order to delete
the correct child instance?
*******Comp #1***********
public var rowArray : Object = new Array() ;
public var counter : Number = 0 ;
//----------- Add Row --------------
private function addRow():Void{
rowArray[counter] = comp#2(comp#1.createChild(comp#2, undefined,
{childRow:rowArray}));
counter++;
}
public function deleteRow(event){
if(rowArray[counter] > 0){
destroyChild(rowArray[counter -1]);
counter--;
}
}
******Comp #2***************
<?xml version="1.0" encoding="utf-8"?>
<mx:HBox xmlns:mx="http://www.macromedia.com/2003/mxml"; >
<mx:Script>
<![CDATA[
import mx.controls.Alert;
public var childRow;

<mx:TextArea width="250" height="100" />
<mx:TextArea width="250" height="100" />
<mx:TextArea width="250" height="100" />
<mx:Button label="Delete" click="deleteRow()" /> <---
**not sure if it is possible to access the delete function in Comp#1
to delete this child component**
