[flexcoders] Re: ModuleLoader.child is null

[valdhor]

I do it a different way than you which you may like to try...

private function onReady(e:ModuleEvent):void
{
     var ml:ModuleLoader = e.target as ModuleLoader;
     // cast the module (the child property of the ModuleLoader) to the
     // ITest interface. If the child implements this interface
     // ichild will not be null.
     var ichild:* = ml.child as ITest;
     if(ichild != null)
     {
         // Pass data to module via interface
         ichild.somedataiwanttopass = this.thedataiwanttopass;
     }
}

Using this I have never found the child to be null (Although I do
check).

implementation of the interface, the child will be null.
