signal and signalcommand problem

Hi,

If i am passing to parameters of the same type in my signal how do I then get them trough injection in my signal command?

consider the following code.

my signal looks like this:
package
{

import org.osflash.signals.Signal;

public class MySignal extends Signal
{
    public function MySignal(...parameters)
    {
        super(String , String);
    }
}

}

and my command like this:
package
{

import org.robotlegs.mvcs.Command;
import org.robotlegs.mvcs.SignalCommand;

public class MyCommand extends SignalCommand
{

    [Inject]
    public var string1:String;

    [Inject]
    public var string2:String;

    public function MyCommand()
    {
        super();
    }

    override public function execute():void
    {
        trace(string1, string2)
    }
}

}

string1 and string2 have the same value and correspond to the value of the 1st parameter passed through my signal.

how do i get the value sent through the second parameter of my signal?

Many thanks
S

   You can't. You have to make a separate value object that stores the 2 values and pass that.

   Same with any DI. You can't have ambiguous injections, so to inject base types you either resort to named injection or you wrap things in strong typing. In the case of the SignalCommandMap the injection is automagic, which is great, but you lose the (ugly) naming option. So strong typing is your only option.

   It can be as simple as SpecialString() or a vo that holds the properties.

   If you really wanted to and can't see the benefit in the strong typing (I like it but you so you know it's not needed) just put the values as named properties on an object or array and dispatch/inject that instead. But you lose all the benefit of type safety.
