Use Flex module:
1.Create a module, add ContextBuilderTag in Declarations tag:

<fx:Declarations>
<mxml:ContextBuilderTag>
<mvcs:MVCSBundle/>
<config:ModelManagerConfig/>
</mxml:ContextBuilderTag>
</fx:Declarations>
2.config:ModelManagerConfig is my custom config: I create a ModelManagerModel single like this:
inject.map(ModelManagerModel).asSingleton();
3.I need to use the ModelManagerModel in a mxml file, but this mxml not mediator.
so how to get the ModelManagerModel ?

• ModelManager.mxml 1.3 KB
• ModelManagerConfig.as 1.64 KB

   Hi,

   The ViewProcessorMap is what you need:

   injector.map(SomeModel).asSingleton();
   viewProcessorMap.map(SomeView).toInjection();
   

   Then you inject SomeModel into SomeView:

   [Inject]
   public var someModel:SomeModel;
   

   Here the documentation:
   https://github.com/robotlegs/robotlegs-framework/tree/master/src/ro...
   https://github.com/robotlegs/robotlegs-framework/tree/master/src/ro...

   You can also search the forum for discussions about viewProcessorMap.

   Hope that helps.

   Thank you very much.
   I found https://github.com/robotlegs/robotlegs-framework/tree/master/src/robotlegs/bender/extensions/viewProcessorMap#shortcut-method-for-the-most-common-case-injection-by-inspection "The Robotlegs 2 view map is designed to allow views to be 'processed'...". Is that mean context don't install the ViewProcessormapExtension in RL.2?
   It works very good without install the ViewProcessormapExtension in RL.2 .

   You're welcome!

   When you create a Context, you tell it to install the MVCSBundle, as you did.
   If you're using the default MVCSBundle, the ViewProcessormapExtension will be installed automatically. Take a look at the MVCSBundle and see all the extensions installed by default:
   https://github.com/robotlegs/robotlegs-framework/blob/master/src/ro...

   No, it doesn't. You can verify that by creating a custom MVCSBundle where you comment out the ViewProcessorMapExtension.
