The solution to this problem: just change the order of the Code

protected void buttonpressed (int buttonid) {

Super.buttonpressed (ButtonID);//This line of code is put here

Display.getdefault (). Syncexec (New Runnable () {
public void Run () {
Localpmtsstreamviewsaction.refreshperspective (Localviewid,
LOCALW);
}
});

}
