Mail Not change state when BlackBerry are Power Off

Question

I have Groupwise with BlackBerry Server Version 4.1.4.28 and I have problems synchronizing the state of the mails read when the PDA's are turned off, summing up if a user reads a post on the Groupwise system in line with the PDA turned off, when you turn on your PDA mail marked as not read this, but everything else is working properly.
We tried to force the synch but neither works.

Answer 1

You aren't explicitly telling the program to repaint itself when you click the button. Otherwise, the only time paintComponent is called is when the object becomes visible, or when it's resized (and the system automatically tells it to repaint).
I tried modifying your code a little and got it to work by passing the TrafficSubPanel as an argument in the constructor for ButtonListener, then stored that as a local variable in the ButtonListener class and when the actionPerformed method is called, just call myPanel.repaint().
There might be other, more standardized ways of doing this though, I'm not sure.
