JTabbedPane adding null components

Question

Hi Everyone,
Riddle me this: I have a JTabbedPane that has custom JPanels in it. When I try and access those JPanels, all I get back is null. I know that the panels have been added because on the UI I can see the tabs. I can also interact with the panels and switch between tabs. It doesn't matter how I add these JPanels, it always returns null.

Now I could just keep an ArrayList of the JPanels on the side for processing, but I would think that would kinda defeat the purpose of the JTabbedPane keeping any kind of model.

Does anyone know what's going on with this?

You're using the wrong method: getTabComponentAt(int) will return the Component used to render the actual tab itself (if you've specified one). You should call getComponentAt(int) instead. I've done exactly the same thing myself before!
