say submitBtn.addEventLIstener(MouseEvent.CLICK, doSomething);

function doSomething(ev:MouseEvent):void {
//do stuff.
}

now you want to call doSomething later on in another function. You cant' pass a mousevent cause one doesn't exist.

how do i fake it?

i think the dispatch route is the way i need to go. I just read a post from rascalpants about something related.

CB. calling doSomething() with out passing a paramter throws an incorrect number of arguement error.

All those ways work.  Plus one more.
submitBtn.addEventListener(MouseEvent.CLICK, doSomething);
 
function doSomething(e:MouseEvent = null):void
{
	trace("MouseEvent.CLICK");
}
doSomething();                                            //Line 1
doSomething(new MouseEvent(MouseEvent.CLICK));            //Line 2
submitBtn.dispatchEvent(new MouseEvent(MouseEvent.CLICK));//Line 3
//Lines 1, 2 and 3 will call the doSomething function without error.
//Lines 2 and 3 do not require " = null" in the parameter of the doSomething function.

maybe you guys are doing something i'm not doing, if I call the function without arguments i'm getting errors.
i'm going with the dispatch route.
thanks all

Eh...  You are making sure that you set the default to null for the function argument, right???  I don't see why it throws out the error message...  Hm...
