Using Flex what event is fired when loading the popup defined in my layer tag?

Question

Here is my Config.xml

...snip...

    <layer label="Pop-up (turn on/off)" type="dynamic" visible="true"  
        alpha="0.8"  
        url="xxx.xxx.xxx">  
        <sublayer id="0" popupconfig="popups/Parcels.xml"/>  -->
    
    </layer> 
</operationallayers>

So, when I click a point on the map a popup appears. That popup displays information about a parcel that was clicked, provides a "zoom to" button.

What event fired to make that occur? I'd like to heavily customize what occurs when I click the map. Bonus points if you can verify which object is being used to render the popup

Parcels.xml

<?xml version="1.0" ?>
<configuration>
    <title></title>

If you are looking to change an event that occurs when you click, you need to be in the mxml of your project. So you need to have your code un-compiled in flashbuilder, but it looks like the mxml, whatever its called in your project - edited
