Use same component in JTabbedPane

Before describing the problem itself, I will explain what I am trying to do.

I'm going to need to use some buttons that will basically do the same thing, except that the actions they're going to apply change from one (JTabbedPane) to another. So I thought that if I used the same component I would save code, besides being more oriented, I'm not sure if what I tried to do is correct, I accept suggestions about it.

I have two problems:

1st: I add the same component in different tabs, and every time I add it I instantiate them (I thought it would be the right thing to do). What happens is that the actions are not happening correctly as I have defined.

2nd: I have defined that the tabs and buttons inside the tabs should be enabled and disabled (disable) when clicking the top buttons (enable and disable), but it is not doing this for everyone.
