FIX: setSelectedTab() In TabControl Does Not Properly Paint Children (223351)

MORE INFORMATION

Steps to Reproduce Behavior

1. Open a new Visual J++ Windows Application project.
2. Add a TabControl and add some TabPages to the control.
3. Add an Edit control and a Button control to each TabPage.
4. Add an OnSelectedIndexChanged event handler to the TabControl.
5. In the event handler, check the text value of the Edit control on the current TabPage; and, if it is not valid, use setSelectedTab() to keep the focus on the current TabPage until the value is valid (see the code sample below).
   
   Results: When setting the TabPage back to the one that had invalid data in its Edit box, the Edit box will not be visible. Call TabControl.setVisible(true) to work around this problem.
