You could try something like this (from
the child)…
parent.destroyChild(this);
I haven’t tried it, but I think it
should work.
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***************

**not sure if it is possible to access the delete
function in Comp#1
to delete this child component**
