RE: [flexcoders] Module Interface Problems

[Roger Gonzalez]

For what its worth, it appears at first glance that your code should
work.
 
Have you tried strong typing rather than using "*"?
 
var results:IResults= IResults(modMyModule2.child)
 
Not sure why it isn't working though, sorry.

        Subject: [flexcoders] Module Interface Problems
        
        
        

        I'm having a problem passing variables from one module to
another via
        an interface.
        
        I have an application that calls a module when it enters a
specific
        state, which works fine. The module is loaded through
<mx:ModuleLoader
        id="modMyModule1" url="myModule1.swf"> and it works as expected.
        
        Within this module, I have a button that when pressed, calls a
second
        module via a module loader, using an interface. I need an
interface,
        as there is a variable that I need to pass between these two
modules.
        Clicking the button runs a couple of functions, ending with:
        
        currentState='Results';
        modMyModule2.url='myResults.swf";
        
        and the states look like:
        
        <mx:states>
        <mx:State name="Results">
        <mx:AddChild>
        <mx:ModuleLoader id="modMyModule2" ready="readyModule(event)"
        error="modErrorHandler(event)" />
        </mx:AddChild>
        </mx:State>
        </mx:states>
        
        So when the module is ready, the following code is invoked in
        modMyModule1:
        
        private function readyModule(evt:ModuleEvent):void
        {
        var ichild:* = modMyModule2.child as IResults;
        if(ichild != null) { ichild.searchResults = arrSearchResults;
        trace("NOT NULL"); }
        else { trace("NULL!"); }
        }
        
        modMyModule2 contains 'implements="IResults"' in it's root
module tag,
        and IResults is defined as follows:
        
        package
        {
        import flash.events.IEventDispatcher;
        import mx.collections.ArrayCollection;
        
        public interface IResults extends IEventDispatcher
        {
        function set searchResults(arrResults:ArrayCollection):void;
        function get searchResults():ArrayCollection;
        }
        }
        
        I have corresponding getter and setter functions in my
modMyModule2,
        but they never seem to get called! For some reason, the
interface is
        always failing, and therefore in my readyModule() function in
the
        first module, it always traces "NULL".
        
        I can access the required variable in the second module via
        parentApplication.modMyModule1.child.arrSearchResults, but I'd
prefer
        to do it via the interface.
        
        I've gone through all the docs, but I can't see what I've done
that's
        different from anything in them, except for the fact that I'm
calling
        a module from a module via an interface.
        
        Can anyone shed some light on this at all?
        
        Cheers,
        K.
