[flexcoders] dynamically loading components

Thu, 11 May 2006 08:44:01 -0700

I'm trying to load dynamically Flex component at runtime from just the component's name (String).
I succeed when I was using Flex2 Beta2 but this does not work anymore with Beta3.
 
Here is the code I am using:
 
     var urlRequest: URLRequest = new URLRequest();
     urlRequest.url = "";
     var context: LoaderContext = new LoaderContext();
     context.applicationDomain = new ApplicationDomain(ApplicationDomain.currentDomain);
     loader.contentLoaderInfo.addEventListener(Event.COMPLETE, handleLoadComplete);  
     loader.load(urlRequest, context);
 
Then in handleLoadComplete:
   var viewClass: Class = Class(loader.contentLoaderInfo.applicationDomain.getDefinition("mycomponent"));
   view = new viewClass();   // <-- it fails here
 
The error I get:
 
InvalidSWFError: Error #2136: The SWF file 'http://localhost:8080/mysamples/core1.mxml.swf' contains invalid data.
 
where core1.mxml.swf is the caller application.
The Flex component mycomponent.mxml is just a VBox, nothing else. When I try to access to the mycomponent.mxml.swf file Í'm getting another error (I don't remember I got it with Flex2 Beta2):
 
TypeError: Error #1010: A term is undefined and has no properties.
 at mx.styles::StyleManager$/http://www.adobe.com/2006/flex/mx/internal::initProtoChainRoots()
 at mycomponent/http://www.adobe.com/2006/flex/mx/internal::_mycomponent_StylesInit()
 at mycomponent$iinit()
I don't know what happened between Beta2 and Beta3, does anyone have any idea ?
 
Thanks
