I have a comboBox component with a CHANGE event listener on it:

dd\_chapter.addEventListener(Event.CHANGE, changeFunction);

function changeFunction(event:Event):void {  
trace(“changed!”);  
}

I want to trigger that event programmatically when the comboBox first gets loaded with data. In AS 2, the syntax would be something like “dd\_chapter.onChange();”. How do I do it in AS 3?

I’ve scoured google for 2 hours and strangely can’t find anything relevant!

Thanks in advance!
