[flexcoders] HistoryManagement Problem

[Bjorn Schultheiss]

Hi,
 
I can't see what 
i've missed here.
 
In this code i have 
a trace in saveState that nevers appears in the console 
panel.
 
<mx:VBox 
 xmlns:mx="http://www.adobe.com/2006/mxml" 
 implements="mx.managers.IHistoryManagerClient" width="400" 
height="100" initialize="init()">
 
 <mx:Script>  <![CDATA[  import 
mx.collections.ArrayCollection;  import 
mx.managers.HistoryManager;        import 
com.xxx.admin.model.AdminModelLocator 
;        
        
        
/////////////////////////        // 
IHistoryState methods        
/////////////////////////        public 
function loadState(state:Object):void 
        
{            if 
(state) 
            
{                
_selectedIndex = 
state.selectedIndex;                
_dataProvider = 
state.dataProvider;            
}        }        public function 
saveState():Object 
        
{             
trace('saveState!');            
var state:Object = 
{};            
state.selectedIndex = 
_selectedIndex;            
state.dataProvider = 
_dataProvider;            
return state;        
}                  public 
function 
init():void       {            
HistoryManager.register(this);       }          
public function set 
dataProvider(value:ArrayCollection):void       
{          _dataProvider = 
value;          HistoryManager.save();       }          
public function set 
selectedIndex(value:Number):void       
{            _selectedIndex 
= 
value;            HistoryManager.save();       
}             [Bindable]       
private var model:AdminModelLocator = 
AdminModelLocator.getInstance();          
[Bindable] private var 
_dataProvider:ArrayCollection;       [Bindable] 
private var 
_selectedIndex:Number;  ]]> </mx:Script>
