Thanks Maury and Clint! This makes sense. We are assigning functions to the result and fault events of the RemoteObject tag. So they will run at that time.
So we can take the results of the event and run the function onGetJobResult() passing the event into this function by placing it in the parentheses. When the function fires we are taking the results and passing it in and converting to an array... So the re: and fe: are just parameters that the function is expecting and the colon is defining it as a ResultEvent or FaultEvent so the function can work with it.... DO YOU SEE THE BIG LIGHT BULB OVER MY HEAD???? :) Wow... makes sense. Thanks again... I am going to break this down and write it out in a way I can understand.
