Loading time issue

Question

hi,
I have an issue with loading custom compont based on title window.
Problem is creating component take too many large time.
This component based on TitleWindow.
And it included
1.HBox which contain 15 buttons(actually it is also an separate component)
2.TabNavigator which contain 9 tabs(7 of them are custom components)
I have use creation policy all for the tabnavigator,because I can't perform my logic using on demand creation policy.
Note:
If I use creation policy auto,then I can't perform my logic.
eg:cann't call reset methods of components, because sometimes,If I I didn't navigate then it has not been created and Object reference is null.then cann't help.
component is very reusable in my system.But it takes too many time to load.
What can I do? Any suggessons?

If you want to go down the creation policy route, set the creation policy to NONE, the use the initialize methods to create them when you have data.
I have a similar project (some code below). In the main <mx:Application/> block, I have a preinitialize method that gets the initial data, the one that is good for tabone then call VSMain.initialize(). This creates the viewstack but only TabOne. The others are created when they are accessed for the first time.
<mx:VBox width="990" paddingLeft="0" paddingRight="0" horizontalCenter="0" height="570" horizontalScrollPolicy="off" verticalScrollPolicy="off">
<mx:ViewStack id="VSMain" width="990" height="570" selectedIndex="0" creationPolicy="none">
     <s:NavigatorContent id="one" label="One">
          <main:TabOne/>
     </s:NavigatorContent>
     <s:NavigatorContent id="two" label="Two" creationPolicy="none">
          <main:TabTwo />
     </s:NavigatorContent>
     <s:NavigatorContent id="three" label="Three" creationPolicy="none">
          <main:TabThree/>
     </s:NavigatorContent>
</mx:ViewStack>
</mx:VBox>
