Hi,

I seem to have been stuck with this issue for a while but could never make
heads or tails out of it. I have a panel with elements executing repeater
elements for my Flex to execute different external code to process the results.
Each of the state produces a different output based on the selection a user
chooses from the panel. Attached is a snippet of both. My issue is that every
time when I execute the code, it always give me this message:

ArgumentError: Error #2025: The supplied DisplayObject must be a child of the
caller.

Does anyone know what I have done wrong here? I do execute each of the
HTTPService requests using event handlers.

Thanks in advance.

Repeater Item Selection:

<mx:AddChild relativeTo="{view}" position="lastChild">
<mx:Panel id="panel3" width="185" x="1092.35" y="180" verticalGap="2"
height="269" title="Filter ">
<mx:Form id="filter5" width="165" click="checkBox_change(event)"
height="225" horizontalScrollPolicy="off" verticalScrollPolicy="off">
<mx:Label id="title5" text="Type" fontWeight="bold" color="navy"

data="{checkBoxRepeater3.currentItem.data}"
change="checkBox_change(event);" />
</mx:Repeater>
