Hi,
I try to use RL for my MobileApplication. The problem occurs when I' am trying to push the view in main navigator stack .
All logic is packed in command. The error was that container is not created , it is strange, because MobileApplication should to create in the begining of the application. I tryied to create a new instance of ViewNavigator and apply it to MobileApplication.navigator, but after that when I tryied to push the new view in navigator stack I receive error:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

at spark.components::ViewNavigator/scheduleAction()[E:\dev\hero_private_beta\frameworks\projects\mobilecomponents\src\spark\components\ViewNavigator.as:1111]

This is the 1111 error line in ViewNavigator.as - explicitFrameRate = systemManager.stage.frameRate;

If I try to push view without using RL, all is ok. navigator var in MobileApplication is not empty and pushView executes normally.
In attached file you can see my command.
Maybe becuase navigator is optimezed in some way from Adobe , and also because RL is optimized to destroy not used components, somewhere they are missed instance.
Any kind of info will be well done. If there is a some sample on mobile application created with RL?

   I found some additional conditions.
   If I replace:
   mainView.navigator.pushView(event.viewClass, event.data, event.transition);
   with
   FlexGlobals.topLevelApplication.navigator.pushView(event.viewClass, event.data, event.transition);

   it's working mainView is injected in my command and also declared in context file
   injector.mapSingletonOf(Gallery1,Gallery1);

   Why it cannot be executed when I using injected mainVIew?

   So finally maybe the correct question is. How to inject main application mxml (FlexGlobals.topLevelApplication) ?

   Off the top of my head, you could try setting up the following in your context:

   injector.mapValue(ViewNavigator, FlexGlobals.topLevelApplication.navigator);
   

   and then injecting the ViewNavigator into a NavigationModel you create to handle that.
