Your example doesn't make sense because if you have the types
FlexModule1 and FlexModule2 in the main app, those classes are linked
into the main app and you've defeated the whole point of modules. You
should be using interfaces instead.
However, by default, a module will be compiled without a package
(actually "package {"} so it won't be of type modules.FlexModule1, it
will just be FlexModule1

Subject: [flexcoders] Problem While Downcasting Flex Modules
HI everyone,
I am facing a problem while down casting the flex module.
I have created two flex modules called FlexModule1.mxml and
FlexModule2.mxml.
These both modules contain the same code.
I have placed FlexModule1.mxml under modules
folder(modules/FlexModule1.mxml) and FlexModule2.mxlm @ application
root.
Here is code for FlexModul1.mxlml (and FlexModule2.mxml as both modules
have identical code)
<?xml version="1.0" encoding="utf-8"?>
<mx:Module xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> " width="400" height="300">
<mx:Script>
<![CDATA[
public function Foo( pstr:String ):String
{
trace( "In Method Foo" );
return "Foo" + pstr ;
}
]]>
</mx:Script>
<mx:Panel width="100%" height="100%">
<mx:Label id="MY_LABEL" text="I AM MODULE-1" fontSize="20"
color="green"/>
</mx:Panel>
</mx:Module>
And here is Main class code.
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml
<http://www.adobe.com/2006/mxml> " layout="vertical"
creationComplete="{loadModule()}">
<mx:Script>
<![CDATA[
import mx.modules.ModuleManager;
import mx.modules.IModuleInfo;
import modules.FlexModule1;
import mx.events.FlexEvent;
import mx.events.ModuleEvent;
import mx.modules.ModuleLoader;
public var moduleLoader:ModuleLoader;
public var moduleInfo:IModuleInfo;
public function loadModule( ):void
{
moduleLoader = new ModuleLoader();
moduleLoader.addEventListener( ModuleEvent.READY ,
moduleReadyEventHandler );
//moduleLoader.url = "FlexModule2.swf"; //This is fine module loaded
moduleLoader.url = "modules\\FlexModule1.swf"; //this fine too
moduleLoader.loadModule();
}
public function moduleReadyEventHandler( evt:ModuleEvent ):void
{
trace( "Module Ready Event Handler" );
this.addChild( moduleLoader );
//(moduleLoader.child as FlexModule2).Foo( '' ) ; // this if fine method
Foo() called
(moduleLoader.child as FlexModule1).Foo( '' ) ; // Null pointer
Exception
}
]]>
</mx:Script>
</mx:Application>
Both modules are loading without any problem but the error occurs when I
try to downcast FlexModule1.mxml. There is no down casting problem with
FLexModule2.mxlm.
I think the problem is with different folder i have used for
FlexModule1.mxml , may b i am wrong.
Please let me know where is the problem.
