Need some guidance on correct usage of Extensions

Hi there,

When I try to use an Extension class (implement IExtension) and I try to declare this variable inside the extension class

    public var injector : Injector;

the injector value is always null. What I'm trying to do is move the blazeds/rpc objects into their own extension (or should that be a bundle) ?

Thanks for Rl2 - everything else is even nicer to work with :)

    LOL with your user name. Naughty ;)

    AFAIK extensions aren't even handled by the injector, i.e. you can't inject instances into them. However, if you simply need a reference to the injector in your extension you can locate it in the context instance that is passed through to the extend method:

    public function extend(context:IContext):void{
        const injector : Injector = context.injector

    Ha! I just noticed that - I'll fix that up ;-)

    Thanks for that info - very helpful....mind if I ask what the purpose of an extension is? Could it be used to say compile the extension to a separate swf/swc to be loaded as RSL?

    Many thanks!

    From the readme:

    An extension integrates a single utility or library into a Robotlegs context.

    You can somewhat compare them to plugins, you can extend the framework functionalities with them.

    and a bundle:

    A bundle bundles up a selection of extensions and configurations into a single package.
