Extending Mediators

Question on if or how this works, or if I'm taking the wrong approach.

I have ViewA that extends Sprite - ViewB and ViewC both extend ViewA - All OK.

ViewB has MediatorB and ViewC has MediatorC.

MediatorB and MediatorC share almost the same code.

My question - Can I have a MediatorA that MediatorB and MediatorC extend?

    Hello Jono,

    The short answer is: yes!

    In the current version of Robotlegs you need to use the third parameter (injectViewAs) of mediatorMap.mapView(). For example:

    mediatorMap.mapView(ViewB, MediatorB, ViewA);
    mediatorMap.mapView(ViewC, MediatorC, ViewA);

    In MediatorA you'd create a view dependency that looks like this:

    public var viewA:ViewA;

    In MediatorB you'd cast that to ViewB:

    public function get viewB():ViewB
        return viewA as ViewB;

    And likewise with MediatorC.

    It's a bit of a pain, but will be made easier in a future version.

    Hope that helps!
