   Hi:
   
   I have a problem with Binding.
   
   My mxml:
   
   ```

                   return securityModel.lang.getRef("Password", true);

   ```
   There are 3 types of binding:
   
   1. **securityModel.lang.user**: this works correctly
   2. **securityModel.lang.getRef('entry')**: this doesn´t work
   3. **passwordLabel**: this is a trick to fix previous mistake
   
   SecurityModel class:
   
   ```
   package com.test.app.models
   {
   
        import com.test.app.beads.models.Model;
       import com.test.app.utils.LanManager;
   
        
        [Bindable]
        public class SecurityModel extends Model
        {
       
   
                private static var _instance:SecurityModel;
                public static function get instance():SecurityModel{
                        return _instance || (_instance = new SecurityModel());
                }
           
           private var _lang:LanManager;
           [Bindable]
           public function get lang():LanManager{ return _lang; }
           public function set lang(value:LanManager):void{ _lang = value; }
   
           /**
                 * Constructor.
                 */
                public function SecurityModel()
                {
                        super();
                        if (_instance) {
                                trace('SecurityModel error');
                                throw new Error("singleton");
                        }
                        _instance = this;
                }
   
           
   
       }
   }
   ```
   
   LanManager class:
   
   ```
   package com.test.app.utils
   {    
        /** Language Manager based on an asociative array */
        [Bindable] 
        public class LanManager extends EventDispatcher
        {
                
                private var _user:String = "user";
   
                public function get user():String
                {
                        return _user;
                }
   
                public function set user(value:String):void
                {
                        _user = value;
                }
   
                
                public function LanManager() {}
                
                
                public function getRef(ref:String=""):String
                {
                        return ref;
                }
                
        }
   
   }
   ```
   
   The classes are simplified.
   
   Why doesn't 2 work? Could it be a bug?
   
   Thanks!!
