Ultialize same component in Jtabbedpane

Question

Before describing the problem itself, let me explain what I’m trying to do.

I will need to use some buttons that will do basically the same thing, only the actions they will apply change from a tab (JTabbedPane) to another. So, I thought that if I used the same component I would save code in addition to being more oriented, I’m not sure if what I tried to do is correct, I accept suggestions regarding this.

I have two problems:

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

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