Jestem naprawdę mylić przez to: niektóre z moich kodu nie działa, gdy uruchomię mój program normalnie w Eclipse, ale robi wok kiedy biegnę przez każdy krok osobno, korzystając z trybu debugowania.kod nie działa, gdy pracuje normalnie, ale praca w debugowania (eclipse)
Kod:
public void showConnectDialog() {
ConnectDialog connectDialog = new ConnectDialog();
connectDialog.setVisible(true);
//Until here, code runs
while(! connectDialog.getConnected()) {};
//The next line does only run in debug
JOptionPane.showMessageDialog(connectDialog, "Connected", "Connected", JOptionPane.INFORMATION_MESSAGE);
}

getConnected() powraca true tak szybko, jak jest podłączony do serwera. Złącze działa na osobnym wątku.
EDIT: Próbowałem umieścić kod w getConnected() podczas blokowania, a następnie działa. Dlaczego to działa, a nie inaczej?
Może to być sytuacja wyścigowa. Czy możesz wysłać kod do 'ConnectDialog'? – austin
Czy oceniasz wyrażenia podczas swoich punktów przerw? Te oceny mogą faktycznie zmienić stan twojego programu (może masz szczęście i zmieniło go w stan roboczy?) –
@austin Kod ConnectDialog ma 700 linii, więc będę umieszczał kod tylko na rzeczywistym łączniku (który jest nadal bardzo długi ...) Nadzieję, że dobrze z tym. – Creator13
