I have this code snippet inside a function that checks if an object exists on stage and removes it:
public function closeContent(e:MouseEvent):void {
removeChild(txt);
removeChild(ldr.content);
removeChild(_closeButton);
container_mc.visible = false;
statusText.text="";
if (contains(submitButton)) {
removeChild(submitButton);
}
if (contains(saveinfoButton)) {
removeChild(saveinfoButton);
}
}
I tried to change stage
with this
and root
but always get this error ArgumentError: Error #2025: The supplied DisplayObject must be a child of the caller
The error signals that you are trying to remove a DisplayObject
with removeChild
that apparently is not a child of the DisplayObjectContainer
this code is executed from.
One way to solve this problem is to check if the object you are trying to remove is actually a child of the container using contains
. You are doing this for some of the objects you are removing (submitButton
and saveinfoButton
), but not for some others.
Try wrapping the removeChild
calls for txt
, ldr.content
and _closeButton
in if statements that use contains
to check whether these DisplayObject
s are in the container.
