Signals & Commands: Multiple Params of Same Type?
Mike Cann
via web
Hi,
Not sure if this has already been asked, but its a common problem I am running into.
When using the Signal command map how does one use multiple params of the same type?
For example suppose I have the following signal:
class MySignal extends Signal
{
public function MySignal()
{
super(MyClass,MyClass);
}
}
And in my SignalContext I map it to a command:
signalCommandMap.mapSignalClass( MySignal, MyCommand);
and then invoke the signal (in a proxy as an example):
class MyProxy extends Actor
{
[Inject] public var signal : MySignal;
public function MySignal()
{
signal.dispatch(new MyClass(), new MyClass());
}
}
In the command how do I then identity each injected MyClass ?
Cheers,
Mike

I believe you need to create a value object to compose your class instances ie. MyVO. The value object will then be strongly typed to your signal.
Hopefully one of the RL guys (or Rob Penner?) can confirm.

Will is correct. By the nature of how the parameters are injected into the command instances values of the same type will not properly inject. Composing a MySignalData object is probably the best bet.
