The context links an Signal class to a Command:
Then inside the model proxy:
[Inject] public var buffermanagerEvent:BufferManagerEvent;
I'm using lots of Signals in that class (around 15), and they
are all dispatched and catched by views for example. But this one
is the only one that's related to a Command in the context (others
are mapped as singletons). The Command is never fired, and no
errors are returned.
