Hi all,

For some reason my userModel is null when I try and use it later in the service

public class AuthenticationService extends Actor implements IAuthenticationService
{
    [inject]
    private var userModel:UserModel;


    private function resultHandler(event:ResultEvent):void
    {
        CursorManager.removeBusyCursor();
        if (event.result.length == 1){

            var test:Object = event.result[0];

            var user:User = new User;
            user.email = event.result[0].mail;
            user.name = event.result[0].name;
            user.SAMAccountName = event.result[0].SAMAccountName;
            user.commentsUsersSelect = event.result[0].commentsUsersSelect;
            user.commentsView = event.result[0].commentsView;
            user.ratingsView = event.result[0].ratingsView;
            //just update the model here instead of calling a command
            userModel.loggedInUser = user;

            dispatch(new UserEvent(UserEvent.USER_LOGIN,user));
        }


    }

configured here:
public class ConfigureModelCommand extends Command

{
    override public function execute():void
    {
        injector.mapSingleton(CommentsModel); 
    injector.mapSingleton(UserModel); 
    dispatch(new ApplicationConfigurationEvent(ApplicationConfigurationEvent.CONFIGURE_VIEW));
    }
}

   Hi Nikos,

   Injected values have to be public - yours is private :)

   An easy mistake to make, and an easy fix too!

   After doing what Stray said, you'll have to fix the [Inject] tag too :)
   Wrong:

   [inject]

   [InJect]

   [INJECT]

   Right:

   [Inject]

   public var someClass:SomeClass;

   Well spotted! I was so distracted by the private I didn't even check the spelling of [Inject].

   haha woops, btw why is it that vars need to be public?

   Just because if they were private the injector wouldn't be able to access them. The actual method of setting values is subject to the same rules as usual.

   The alternative is setter injection - private var, and a public setter func, marked with inject.
