Dear Richard Szalay,
i go through your answers regarding bubbling, i want explore bubbling more. Please see my sample below

<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" xmlns:view="com.view.*"  >

} ]]>

In my custom event class i set bubbling=true, cancelable=true

I can understand from previous answer that bubbling only affects UI components; events fired from custom classes will not bubble, even if the bubbles argument is set to true.

My question is how can i prevent panelClickHandler function got fired when i click button in the "Load" (custom component)??

pleas explain bubbling with good example ( like to have with custom event classes)?
