Are you sure that an exception doesnt get thrown before the print after?

When a line of code that "should" get executed doesnt, you can usually bet on an Exception. Surely you have all this in a try catch block. Are you simply catching all exceptions?

well, the stacktrace says NPE, because i need an object that isnt created

when i push a ceratin button that code should be executed:
here's how i have it:
[code] public FrameA() {
enableEvents(AWTEvent.WINDOW_EVENT_MASK);
controlaBotoes = new ControlaBotoes(this);
controlaBotoes.comuta(false);
try {

jbInit();
// isto aqui n

CASE SOLVED
never mind, i had a typo
thanks anyway!
