Getting blank screen in Swing Aplication

Hi All,
I am developing a swing application, in which I have JFrame and this JFrame contains many panels and each panel contains JTables and JButtons, and JLabels and I applied TableCellRenderer to the each of the column of JTables.
But when I returns to this page from some other pages, I am getting a blank screen, and when I move my mouse over the JButtons or JTable, the page is displaying.

I don't know, what is the problem.

If any one had this problem before, please let me know, how you solved it or please provide me what all may be the reason behind it ?

Thanks In Advance

Renjith M

This almost always is caused because you are not switching the panels properly.

You got two options
1) Use card layout
2) User parent.add and also call revalidate and repaint after the add call.
