I have imported a swf (not created with Flex, i.e. non-framework) into a Flex application. Once loaded, I would like to access movieclips within that imported swf. Looking at Adobe's docs (http://livedocs.adobe.com/flex/3/html/help.html?content=controls_15.html), it seems straightforward; however, their examples are between a Flex app and an imported swf (created with Flex).

Like their example, I'm trying to use the SystemManager to access the imported swf's content; however, I receive the following error:

TypeError: Error #1034: Type Coercion failed: cannot convert flash.display::MovieClip@58ca241 to mx.managers.SystemManager.

Is this error occurring because I'm importing a non-framework swf into a framework swf? Thanks in advance for any assistance.

Code:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">

<mx:SWFLoader source="assets/test.swf"  id="loader"  creationComplete="swfLoaded()" /> 

<mx:Script>
 <![CDATA[

  import mx.managers.SystemManager;

  [Bindable]
        public var loadedSM:SystemManager;


  private function swfLoaded():void 
  { 
   loadedSM = SystemManager(loader.content);
  } 
 ]]>


</mx:Script>
</mx:Application>

Was test.swf created with an earlier AS version? According to this swfs published for AS 1.0/2.0 runs in a different AS virtual machine than AS 3.

The parent AVM2 SWF file will not have access to the properties, methods, or objects of the loaded AVM1Movie object.

You can access them directly, using their instance names.

private function swfLoaded():void {
    var clip1:MovieClip = MovieClip(loader.content.myClip1);
    var clip2:MovieClip = MovieClip(loader.content.myClip2);
    // ...
}

  • I tried the following... (please note that the movieclip/symbol was named firstFloor, and the instance of the movieclip was named "firstFloor_mc", and the movieclip was exported as a Class named firstFloor. – squared May 06 '10 at 20:22
  • 1. var clip1:MovieClip = MovieClip(loader.content.firstFloor); error: 1119: Access of possibly undefined property firstFloor through a reference with static type flash.display:DisplayObject.

    2. var clip1:MovieClip = MovieClip(loader.content.firstFloor_mc);error: 1119: Access of possibly undefined property firstFloor through a reference with static type flash.display:DisplayObject.     – squared May 06 '10 at 20:22
  • The second option is correct, assuming the clip is on the first frame of the stage. That second error message is the same as the first. Copy/paste error or did you forget to save the file when you tested the second style? :) – Cory Petosky May 06 '10 at 22:03
