If your XML says to instantiate a Foozle, there needs to be a compiled Foozle class somewhere. Either that class is in the main Application SWF or it is in some SWF (probably a "module SWF" which works with Flex's module-loadind APIs) that gets loaded -- possibly on demand -- by the main SWF. If the dynamically instantiated classes can't be in the main SWF, then you need to look into modules.

I need to create object instances based on XML data. The component creating the instances isn't aware of what objects might get created. So I would need to declare every type of object just in case. Which means it's not dynamic at all, as soon as there is a new Object I need to modify the code to allow for it.

It needs to be compiled into the swf in order to instantiate it dynamically. My personal preference is to do this with a static code block: { MyClass1, MyClass2 } regards, Christophe -- Christophe Herreman http://www.herrodius.com <http://www.herrodius.com> http://www.pranaframework.org <http://www.pranaframework.org> 2008/4/18, Dale Fraser <[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]> >: Anyone tell me why this doesn't work. var ClassName:String = 'views.pr.ProjectView'; var ClassReference:Class = getDefinitionByName(ClassName) as Class; var instance:UIComponent = new ClassReference(); child.addChild( instance ); ReferenceError: Error #1065: Variable ProjectView is not defined. at global/flash.utils::getDefinitionByName() at Main/addTab()[C:\ Central\Flex\src\Main.mxml:86] at Main/treeChanged()[C:\ Central\Flex\src\Main.mxml:52] at Main/__menuTree_click()[C:\ Central\Flex\src\Main.mxml:138] Regards Dale Fraser http://learncf.com <http://learncf.com/> http://flexcf.com <http://flexcf.com/> -- Christophe Herreman http://www.herrodius.com <http://www.herrodius.com> http://www.pranaframework.org <http://www.pranaframework.org>
