I've reccently run into issues with indexing my tabs and though I'd give it some concrete ordering by using the `setComponentAt` method. Here's my code:

```
public ContainerPane() {
    this.setLayout(new BorderLayout());
    myPlayerManagerPane = new PlayerManagerPane();
    myGameManagerPane = new GameManagerPane();
    myCharacterManagerPane = new CharacterManagerPane();

    myPaneTab = new JTabbedPane(JTabbedPane.TOP);
    myPaneTab.addTab("Character",myCharacterManagerPane);
    myPaneTab.addTab("Player",myPlayerManagerPane);
    myPaneTab.addTab("Games",myGameManagerPane);
    System.out.println(myPaneTab.getTabCount());
    //myPaneTab.setEnabledAt(1, false);
    //myPaneTab.setEnabledAt(2, false);
    myPaneTab.setComponentAt(0, myPlayerManagerPane);
    myPaneTab.setMnemonicAt(0, KeyEvent.VK_1);
    myPaneTab.setComponentAt(1, myCharacterManagerPane);
    myPaneTab.setMnemonicAt(1, KeyEvent.VK_2);
    myPaneTab.setComponentAt(2, myGameManagerPane);<---outOfBoundsException
    myPaneTab.setMnemonicAt(2, KeyEvent.VK_3);
    add(myPaneTab);
}

```

So for the count I have, 3 tabs (according to me, and `getTabCount()`), and I am counting from 0 (correct?). I'm setting the last index the last component that I have. But I still have this printing to screen:

```
3 <---from tabCount
Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: 2 >= 2

```

Where am I tripping up, is there an easier way to order my panes?

Edit: Commenting out the `setComponent` methods, and putting in a for loop I get this output:

> 
> There are 3 tabs!  
> 
>  Tab at 0 is Character  
> 
>  Tab at 1 is Player  
> 
>  Tab at 2 is Games
> 
> 
> 

And uncommmenting one pair of methods at a time, I get only 2, of the one I've not overwritten, and one of the ones I've now set.

Is `setComponentAt` removing duplicates? Should I ever have fewer than 3 tabs with my set up? Does JTabbedPanel have odd behaviour for duplicate panes?
