Need to repaint a dialog after modifying its components

I am attempting to repaint a dialog after removing the components from its content pane and adding new ones.  I've tried calling invalidate and repaint, but I get various issues ranging from the screen going blank and me having to move the window for it to repaint to the old components rendering until I move the window and it repaints.

How can I reliably get the window to completely re-layout and re-paint?

I am using Swing / Java 1.6.

It would appear that calling validate() then repaint() on the root (using SwingUtilties.getRoot) works.  Is there a better / more reliable way to do this?
try invoking just validate method!
validate is what you need to call if any comp is added/removed!
