Alex thanks for your reply, basically my application has total 10 screens and
6 out 10 screens will be used in other flex applcations , so what i have
decided is to make all 10 screens as module and 10 presenter classes for each
module.
(Do you think it is a good approach?). Now as you said use Interface, their is
no problem in using interface, but my presenter class needs to know the actual
Module name so that i can access the individual components of modules in
presenter class. one more thing my Modules are passive view . can you help me
how to solve this problem. becuse my presenter classes are totaly dependente
view(Module)..

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"; 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"; 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.
