[flexcoders] Data changed in xml file does not updated in

[jam35bond]

Hi all,
My mxml has 2 components like this:
<mx:XML id="bagXML" source="../../data/bag.xml" />
<mx:Repeater id="bagRepeater" dataProvider="{bagXML.image}">
  <mx:Image source="{bagrepeater.currentit...@src}" 
width="130" height="130" click='showSWF2(event, 
event.currentTarget.getRepeaterItem()....@swf);'/>
</mx:Repeater>

I have to recompile the program with Flexbuilder everytime I got data changed 
in the XML file.

How do I do that if I only want to get the front end display data changed by 
only update the XML file without recompiling the whole program?

I am using Flex SDK3.2
Thanks
