Hi. Sorry, my english is bad (is very ...telegraphic), I speak spanish.

I have a JTable with custom editors (JPanel with a JTextField inside). This JTable is inside a JInternalFrame (MDI application). I set a input verifier to the JTextField, its show a error dialog (is a JOptionPane, I use the workaround for the #4532517), but when press "Ok" in the error dialog, the focus goes to the JToolBar of the main JFrame (???), not to the JTextField.

PD: I try with textfield.requestFocus() in the shouldYieldFocus(), but this not work. Searching, I find this article:
http://www.javaworld.com/javaworld/j...2-traps_p.html
but the propose solution (call the requestFocus() in SwingUtilities.invokeLater()) doesnt work for me (the call to requestFocus() and requestFocusInWindows() return false; textfield.isFocusable() return true, but textfield.isDisplayable() return false! Some idea?)

Thanks in advanced.
