So you are trying to dispatch events from your Product object? Your Product
object doesn't have dispatchEvent() method on it since it doesn't extend
EventDispatcher, hence the complier message. Instantiating a new
EventDispatcher instance won't help because nothing is registered to listen
for events from it. Look at the addToQuote() function. That instance was
created there, but how could anything outside of that function register a
listener with it if the instance didn't exist before that call?
What you have to do is dispatch that event on an EventDispatcher connected
to the stage. Your Product instance isn't connect to the stage. I would
say consider dispatching the event from outside your Product class.
Register a function on that mouse listener, call addToQuote(), then after
that dispatch an event using the UIs EventDispatcher.
public function handleClick() : void {
var product : Product = ... // get the currently selected product
product.addToQuote();
dispatchEvent( ... );
}
<mx;Button click="{handleClick()}"/>
I hope that helps, but it's hard to say exactly what you should do given I'm
not sure who is listening and how they were registered.
