Dialog not reflecting new values

Hi,

I have a problem in swings as follows
I have an application which has a tab1 which contains a Jtable.On clicking a cell in Jtable a JDialog appears showing some more info on the cell clicked.

In clearer terms this is what i would like to do

Steps:
- After running the below code you get a 3 buttons Lookup1,Lookup2 and Refresh and also 2 tabs with two different Jtables.
- When i press the first tab and say Lookup1 the tab1->table loads.
- Right click on a row, a dialog1 comes showing first coloumn data of the row.
- Now go to tab2 and press Lookup1 button tab2->table loads,repeat the above step another dialog2 appears.
- Now i press Refresh button the table's only load and dialog remains same.
- Now again when i go to tab1-table and right click on a row the corresponding dialogs contain the old value and do not reflect new value.
I want the last point to happen...????
Please help me in tweaking the code.

Thanks

This is a ton of code but I would encourage you to add some debugging statements that would help you see what is going on. As an alternative, are you using some sort of IDE like Eclipse or NetBeans? They are incredibly valuable in determining issues.
