ArrayCollection loop through for matching items

Question

Hi

I hope someone can help me.....

i am trying to build a dynamic form for a questionnaire module. Building on some previous posts I am using the process similar to that in question "http://stackoverflow.com/questions/629021/how-to-generate-a-formmxform-dynamically-in-flex" i have managed to prove out the fact of extending the XML to include a calendar, combobox etc.

my problem is that now need to get the data from an ArrayCollection rather than from an xml file. I am looking to loop through the AC and where type = "text" render a textinput field, where a type ="calendar" render a Calendar etc etc.

my code so far just looking at a textinput field (and sorry for all the comments included ;) is:-

   [Bindable]
  public var AC:ArrayCollection = new ArrayCollection( [
  {type:'text', direction:'horizontal', tooltip:'test tooltip', label:'my textbox label', id:'1'},
          {type:'text', direction:'horizontal', tooltip:'another tooltip', label:'another label', id:'2'}
     ]);



  private function init():void

  {     
      var form:Form = new Form();

          for each(var elements:String in AC)

   {  
                          switch( [email protected]()) 
                            { 
                                  case "text": 

                   var fi:FormItem = new FormItem(); 
                       //   fi.toolTip = elements.tooltip.toString();
                                            //   fi.required = getglobalprofile.required.toString();
                                            //   fi.direction = getglobalprofileb[i].@direction;

                      var li:Label = new Label();
                                          //  li.text = getglobalprofileb[i].@label;
                                          // li.width = 100;

                      var ti:TextInput = new TextInput(); 
                                             ti.text = "test"; 
                                      ti.width = 200;

                       form.addChild(fi);
                       fi.addChild(li);
                       fi.addChild(ti);

             //         break; 
                            }
             }    

                    this.addChild( form); 
           }   

 ]]>
    </mx:Script>

 <!-- Data grid added just to check that AC getting data-->

 <mx:DataGrid id="profile" selectedIndex="1" dataProvider="{AC}" width="100%" height="50%"  />

     <mx:Form  id="form" name="form">

     </mx:Form>

if you are interested in the working xml version (rendering only) let me know and i will post this as well

Answer 1

I have found the answer to the first part of this problem of getting the form to render with a simple request to the DB using a RO call.

The next issue is how to get the form to save when i don't "know" the field ID, how many there are or what type of field it is.........

another post methinks!

hope this is of use to someone.

          for each(var elements:Object in getglobalprofileb)
