actionscript 3 - Load swf on loaded swf? -

i'm on project created in flash builder 4.7 , flash professional cs6, nice. need project load's swf inside "preloaded swf",

• the first swf, loads second swf,

• this second swf "home" of project.

at point, work's perfectly. when "home" try load other external swf, says :

[ioerrorevent type="ioerror" bubbles=false cancelable=false eventphase=2 text="error #2124"]

the code of first swf:

public class initialswf extends movieclip {    private var _loader_:loader;    private var _applicationcontent_:displayobject;    private var _loadercontent_:movieclip;    private var _loadericon_:movieclip;    public function initialswf()   {      super();      _loader_ = new loader();      _loader_.contentloaderinfo.addeventlistener(event.complete,_oncomplete_,false,0,true);      _loader_.contentloaderinfo.addeventlistener(ioerrorevent.io_error,_onioerror_,false,0,true);      _loader_.contentloaderinfo.addeventlistener(progressevent.progress,_onprogress_,false,0,true);      _loader_.load(new urlrequest("home.swf"));   }    private function _oncomplete_(param1:event) : void   {      _applicationcontent_ = _loader_.content;      _applicationcontent_.visible = true;      stage.addchild(_applicationcontent_);      _applicationcontent_.addeventlistener("onapplicationcomplete",_onapplicationcomplete_,false,0,true);      _loader_.contentloaderinfo.removeeventlistener(event.complete,_oncomplete_);      _loader_.contentloaderinfo.removeeventlistener(ioerrorevent.io_error,_onioerror_);      _loader_.contentloaderinfo.removeeventlistener(progressevent.progress,_onprogress_);      _loader_.unload();      _loader_ = null;   }    private function _onapplicationcomplete_(tmpevt:event) : void   {      _applicationcontent_.removeeventlistener("onapplicationcomplete",_onapplicationcomplete_);      _loadercontent_.addeventlistener("loaderout",_onloaderout_,false,0,true);      //   }    private function _onloaderout_(param1:event) : void   {      _loadercontent_.removeeventlistener("loaderout",_onloaderout_);      _applicationcontent_.visible = true;      stage.removechild(this);   }    private function _onioerror_(tmperror:ioerrorevent) : void   {       trace(tmperror);   }    private function _onprogress_(param1:progressevent) : void   {      var _progress_:number = math.round(param1.bytesloaded / param1.bytestotal * 100);      //do animation loading   } 

and homeswf:

public class secondaryswf extends sprite {      private var _loader_:loader;      private var _loadercontent_:movieclip;      private var _loadericon_:movieclip;      private var _applicationcontent_:displayobject;      public function secondaryswf()     {         this.addeventlistener(event.added_to_stage,this._gologin_,false,0,true);     }      public function _gologin_(tmpevent:event)     {         _loader_ = new loader();         _loader_.contentloaderinfo.addeventlistener(event.complete,_oncomplete_,false,0,true);         _loader_.contentloaderinfo.addeventlistener(ioerrorevent.io_error,_onioerror_,false,0,true);         _loader_.contentloaderinfo.addeventlistener(progressevent.progress,_onprogress_,false,0,true);         _loader_.contentloaderinfo.addeventlistener(httpstatusevent.http_status, httpstatushandler);         _loader_.load(new urlrequest("secondaryswf.swf"));     }      private function httpstatushandler(event:httpstatusevent):void {         trace(event);     }      private function _oncomplete_(param1:event) : *     {         _applicationcontent_ = _loader_.content;         _applicationcontent_.visible = true;         stage.addchild(_applicationcontent_);         _applicationcontent_.addeventlistener("onapplicationcomplete",_onapplicationcomplete_,false,0,true);         _loader_.contentloaderinfo.removeeventlistener(event.complete,_oncomplete_);         _loader_.contentloaderinfo.removeeventlistener(ioerrorevent.io_error,_onioerror_);         _loader_.contentloaderinfo.removeeventlistener(progressevent.progress,_onprogress_);         _loader_.unload();         _loader_ = null;         this.removeeventlistener(event.added_to_stage,this._gologin_);     }      private function _onapplicationcomplete_(param1:event) : void     {         _applicationcontent_.removeeventlistener("onapplicationcomplete",_onapplicationcomplete_);         _loadercontent_.addeventlistener("loaderout",_onloaderout_,false,0,true);         // ..     }      private function _onloaderout_(param1:event) : void     {         _loadercontent_.removeeventlistener("loaderout",_onloaderout_);         //_applicationcontent_.visible = true;         //stage.removechild(this);     }      private function _onioerror_(tmperror:ioerrorevent) : void     {         trace(tmperror);     }      private function _onprogress_(param1:progressevent) : void     {         var _progress_:number = math.round(param1.bytesloaded / param1.bytestotal * 100);         // ..     } } 

consolechromeswf <-this image of google console.log, , catch this:

• start initialswf
  
• load homeswf
  
• complete loaded of homeswf
  
• start homeswf
  
• the link of secondary swf (censored/hidden public)
  
• load secondaryswf
  
• error
