I am creating a project on RobotLegs + Flex 4 +Spring. I have implemented one command perfectly but when i map second command RobotLeg throws error:

Main Thread (Suspended: Error: Injector is missing a rule to handle injection into property "addProjectResultEvt" of object "[object AddProjectResultCommand]". Target dependency: "com.educomp.intelftp.events::AddProjectResultEvevnt", named "")

   Hello Gaurav,
   I think, it's an event name collision. The constants of the 2 events have the same value of "Sucesses " and „Fail“.

   You have these constants:

   -GetProjectResultEvent

   public static const GET_PROJECT_RESULT_SUCCESS:String = "Sucesses";
   public static const GETPROJECT_RESULT_FAIL:String = "Fail";

   -AddProjectResultEvevnt

   public static const SUCESSES:String = "Sucesses";
   public static const FAIL:String = "Fail";

   and these mappings:
   commandMap.mapEvent(GetProjectResultEvent.GET_PROJECT_RESULT_SUCCESS,GetProjectResultCommand);

   commandMap.mapEvent(AddProjectResultEvevnt.SUCESSES,AddProjectResultCommand);

   Solution:

   • specify the eventClass for a stronger mapping (3rd parameter of commandMap.mapEvent):

   commandMap.mapEvent(AddProjectEvevnt.ADD_PROJECT,AddProjectCommand, AddProjectEvevnt);
   commandMap.mapEvent(GetProjectResultEvent.GET_PROJECT_RESULT_SUCCESS,GetProjectResultCommand, GetProjectResultEvent);

   • declaring constants like the following would be better

   GetProjectResultEvent

   public static const GET_PROJECT_RESULT_SUCCEEDED:String = "GetProjectSuceeded";
   public static const GET_PROJECT_RESULT_FAILED:String = "GetProjectFailed";

   AddProjectResultEvevnt

   public static const ADD_PROJECT_SUCCEEDED:String = "AddProjectSuceeded";
   public static const ADD_PROJECT_FAILED:String = "AddProjectFailed";

   or using Event’s fully qualified class path or other unique values of your choice:

   public static const ADD_PROJECT_ SUCCEEDED:String = „com.educomp.intelftp.events. AddProjectResultEvevnt.AddProjectSuceeded “;

   public static const GET_PROJECT_RESULT_ SUCCEEDED:String = „com.educomp.intelftp.events.GetProjectResultEvent.GetProjectSuceeded”
   .Suceeded“;

   Info about custom events and creating static constants for the Event.type property: http://help.adobe.com/en_US/Flex/4.0/UsingSDK/WS2db454920e96a9e51e6...

   Also, it would be a good idea to override the clone method of your custom events: http://knowledge.robotlegs.org/kb/application-architecture/why-does...

   Let us know how it goes.
   Cheers,
   Ondina
