    Cannot access binded variable inside a resultEvent

    David Brannan

      Hello from Alaska - it was only -47 F this morning.


      I'm adding a flex multi-file uploader to my application and ran into a sticking point (going on 3 days now), and I hope someone with a kind heart and more IQ points than I was blessed with can help.


      In order to upload files to a CF uploader I am passing in two variables (jsessionID + myQuestionID).


      This all takes place in a function as follows:


      // initUploader is called when account info loads

      public function getSessionInfoResult(event:ResultEvent):void{       


      // Get jsessionid & questionid (final directory) for CF uploader

      myToken = roAccount.getSessionToken.lastResult;

      myQuestionID = questionsDG.selectedItem.QuestionID;


      var postVariables:URLVariables = new URLVariables();

      postVariables.jsessionid = myToken;

      postVariables.questionid = myQuestionID;            


      multiFileUpload = new MultiFileUpload(

















      I've set myQuestionID as a public binded variable at the top of my actionscript block as follow:


      public var myQuestionID:int;


      I can see myQuestionID elsewhere in my form, but not inside the getSessionInfoResult function.


      No matter how I try to bind it - private, public, create it's own function, it just won't show up in getSessionInfoResult.


      Any ideas out there would sure be appreciated.

          This code shows it is visible within the result handler. Something else must be wrong with your code.



          <?xml version="1.0" encoding="utf-8"?>
          <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"
                import mx.rpc.events.ResultEvent;
                [Bindable] public var myQuestionID:int;   
                public function getSessionInfoResult(event:ResultEvent):void{         
                  myQuestionID = 59355;
            <mx:HTTPService id="svc" url="http://www.google.com" 
              result="getSessionInfoResult(event);" resultFormat="text"/>
            <mx:Text text="{myQuestionID}"/>

            Hello Greg - thank you for taking a bit of your day to help.


            If I hard code myQuestionID = 59355; into the getSessionInfoResult it is visible (I did that for debuggin ensure my uploader works - and it does).


            However, if I try to bind a selected item from my grid inside getSessionInfoResult - like:


            myQuestionID =questionsDG.selectedItem.QuestionID;


            then it shows a value of null.


            I cannot get myQuestionID =questionsDG.selectedItem.QuestionID; to work anywhere between my action script tags, but it works fine in the form itself.


            Attached is updated code.
