LoaderInfo null inside createComplete handler function

Question

I encoded this little snippet to show that I do not understand:

<?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="init()"> <mx:Script> public function init():void { txtName.text = this.loaderInfo.toString(); } </mx:Script> <mx:TextInput x="50" y="10" id="txtName"/> </mx:Application> 

I get the following error:

 TypeError: Error #1009: Cannot access a property or method of a null object reference. at Teste/init()[C:\Lucas\flex\AppName\src\Teste.mxml:5] at Teste/___Teste_Application1_creationComplete()[C:\User\flex\CornetaRecorder\src\Teste.mxml:2] at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.core::UIComponent/dispatchEvent()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:9298] at mx.core::UIComponent/set initialized()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:1169] at mx.managers::LayoutManager/doPhasedInstantiation()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\managers\LayoutManager.as:718] at Function/http://adobe.com/AS3/2006/builtin::apply() at mx.core::UIComponent/callLaterDispatcher2()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8628] at mx.core::UIComponent/callLaterDispatcher()[C:\autobuild\3.2.0\frameworks\projects\framework\src\mx\core\UIComponent.as:8568] 

Can't I read loaderInfo inside the creationComplete handler? I am trying to pass a string from html to my flash component, so I need to get loaderInfo to work.

Answer 1

The loaderInfo object is not available until the FlexEvent.APPLICATION_COMPLETE event occurs. Try changing the code:

 <?xml version="1.0" encoding="utf-8"?> <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" applicationComplete="init()"> <mx:Script> <![CDATA[ public function init():void { txtName.text = this.loaderInfo.toString(); } ]]> </mx:Script> <mx:TextInput x="50" y="10" id="txtName"/> </mx:Application> 

Note line 2 that the creationComplete been changed to applicationComplete .

Hope this helps!
