flex dynamic mxml component adding

Hello,

I'm attempting to add mxml components dynamically to a display list within a form and am having issues.  

The form is intended to allow users to conduct customer interviews.  After selecting the interview type from a combo box, questions are retrieved via web service (working) and then added to a question object (custom AS3 class ).
These objects are then added to an array collection.  Then I create another array collection and add my mxml question 'widget' and map it to one of the existing question objects. When I run the application and refresh the data provider of the display list (using custom item renderer), the components will display but not the mapped question object values (i.e. the question text).

How do I get the mapped question object values to display within the component?



Here is how I am building the list data provider:

                                //save web service result (XML) for local use
                        var xmlResult:XML=new XML(event.result);

                        //create array collection to hold question object values
                        var questionsAC:ArrayCollection=new ArrayCollection();

                        //loop through all questions in result
                        for each (var question:XML in xmlResult.Table)
                        {
                              //create question object
                              var tempQuestionAdt:InterviewQuestionsAdt=new InterviewQuestionsAdt;
                              
                              //load question object values from XML input
                              tempQuestionAdt.LoadFromXML(question);
                              
                              //add questions object to array collection for later use
                              questionsAC.addItem(tempQuestionAdt);
                        }
                        
                        //create array collection to hold mxml components
                        var displayQuestionsAC:ArrayCollection = new ArrayCollection();
                        
                        try
                        {
                  // loop through all questions in questions array and assign objects to mxml components
                              for (var x:int=0; x < questionsAC.length; x++)
                              {
                                    //create new mxml component
                                    var thisQuestionWidget:InterviewQuestionWidget=new interviewQuestionWidget();
      
                                    //remap array collection object to custom object class
                                               
                                               
                                    //var tempQ:InterviewQuestionsAdt=questionsAC[x] as InterviewQuestionsAdt;

                                    //define a unique 'id' value for each created mxml component
                                    thisQuestionWidget.id="wgtQuestion" + x.toString();
                                    
                                    //set current question object to mxml component value
                                    thisQuestionWidget.QuestionAdt=tempQ;
                                    
                                    //Alert.show(tempQ.question);
                                    //thisQuestion.Activate();
                                    //thisQuestion.invalidateDisplayList();
                                    
                                    //add mxml component to display list array collection
                                    displayQuestionsAC.addItem(thisQuestion);
                              }
                              
                              //reset display list data provider
                              listQuestions.dataProvider=displayQuestionsAC;
                              listQuestions.invalidateDisplayList();
                        }
                        catch (err:Error)
                        {
                              //display error
                              Alert.show(err.message);
                        }



Here is the mxml List:

<mx:List x="10" y="184" width="698" height="414" id="listQuestions"  >
                  <mx:itemRenderer>
                                                
                                          <mx:Component>
                                                <ns2:InterviewQuestionOuterWidget  >
                                                
                                                </ns2:InterviewQuestionOuterWidget>
                                          </mx:Component>

                                    </mx:itemRenderer>
                  
                  </mx:List>
