Hi guys!

normally i use this fix http://sjhewitt.co.uk/2010/02/robotlegs-and-as3signals-injecting-interfaces-and-named-arguments/
for RL1, so is there any other fix or way/workaround like this for RL2?

Thanks

   Hello,

   I don't know if the new Signal command map for Robotlegs2 has a solution for your problem, but here it is, in case you haven't seen it already:

   We've provided another mechanism: all payload values are optionally passed to the execute method of the command.
   All you need to do is turn off the automatic injection of payload values into the command and add method parameters corresponding to the signalValues to the execute method.

   //InjectionTestSignal
   public function InjectionTestSignal ()
   {
       super(String, String, IList, IList);
   }
   
   //InjectionTestCommand
   public function execute(s1:String, s2:String, l1:IList, l2:IList ):void{
       //do something crazy!
   }
   
   //CommandConfig
   signalCommandMap.map(InjectionTestSignal)
       .toCommand(InjectionTestCommand)
       .withPayloadInjection(false); //don't forget this one
   

   You have to set withPayloadInjection to false otherwise it will error out, since it'll try to map two different values to the same type (String and IList).

   Haven't tested it out, but it should definitely work., if not: let me know.
   TBH, we never had this use case in mind, but we did try to make everything a bit more versatile; I hope we succeeded (considering the amount of brain power we put into :) )

   Hi creynders

   It seem to work but i've to change from...
   -----------------------------------------------------------------------
   public class InjectionTestCommand extends Command
   -----------------------------------------------------------------------
   to
   -----------------------------------------------------------------------
   public class InjectionTestCommand
   -----------------------------------------------------------------------
   so i can freely do
   -----------------------------------------------------------------------
   public function execute(s1:String, s2:String, l1:IList, l2:IList ):void{....}
   -----------------------------------------------------------------------

   then I just realized that i didn't need to "extends Command" am i right?

   because it just working(yeah!), but i didn't know what gonna break if i didn't extend Command...

   Thanks

   You don't have to extend Command it is just a convenience class. And, in this case it is not very convenient, so you don't need to use it :)
