actionscript 3 - Adobe AIR 3.4 saving/writing XML data to iOS -

i'm trying save xml data ipad 4 air 3.4 ios , can't tell if working or not. no events being fired apparently. appreciated.

    private function savedata(e:mouseevent):void {             var name:string = assetmanager.save_annotations_name                     var file:file = new file()                       file = file.applicationstoragedirectory.resolvepath(name + "xml");         var xml:xml = _canvas.getobjectdata(formattype.degrafa);                     var filestream:filestream = new filestream();         filestream.open(file, filemode.write);         filestream.writeutf(xml.tostring());           filestream.addeventlistener(progressevent.progress, onfilestream);         filestream.addeventlistener(event.activate, onfilestream);         filestream.addeventlistener(event.open, onfilestream);         filestream.addeventlistener(event.deactivate, onfilestream);         filestream.addeventlistener(ioerrorevent.io_error, onfilestream);         filestream.addeventlistener(event.complete, onfilestream);        }      protected function onfilestream(event:event):void     {         trace('filestream event ' + event)         filestream.close();       }    

i seemed have fixed this:

    private function savefile(event:mouseevent):void     {           var xml:xml = _canvas.getobjectdata(formattype.degrafa);         trace('xml ' + xml.toxmlstring())         var file:file = file.documentsdirectory.resolvepath("annotations.xml");                  var filestream:filestream = new filestream();            filestream.openasync(file, filemode.write);           filestream.writeutfbytes(xml.toxmlstring());          filestream.addeventlistener(event.close, fileclosed);           filestream.close();            function fileclosed(event:event):void {               trace("file saved");            }             }
