Well, my events extend CairngormEvent, so I can
technically upcast 'em when they get in the Command's execute method. I
know Steven didn't really dig this idea, but if you case the type, you can
compare to the Event's constant like:
public static const EVENT_DOSOMETHING:String =
"doSomething";
function execute(event:CairngormEvent)
{
switch(event.type)
{
case
MyEvent.EVENT_DOSOMETHING:
someMethod ( MyEvent(event).someTypeSafeProp);
break;
}
}

The only typesafe solution i can think of, is to abandon
CairngormEvents and replace them by methods of the FrontController. Most of the
apps i've seen so far don't make use of the runtime changeability anyways. What
do we loose if we do it like that?
Cheers,
Ralf.

I'm with you. I've been determing type of event based on the event.type in the Command's execute method to get my
strong-typing back.

Its really a pity, that we loose all the nice type information
while going all the way through Cairngorm.
Cheers,
Ralf.

Hi,
The
delegate function thinks you just have a CairngormEvent. I think
you
just need to check to make sure the event you received is your
custom
event type and then cast it.
so:
if (eventHere is
LoadScorecardEvent)
{
del.getScorecard(
LoadScorecardEvent(eventHere).scorecardId
);
}
else
{
// do nothing, or raise
error, or log warning, or whatever.
}
best of
luck,
Thunder

But this bombs out with a error about scorecardId not in eventHere.
