xtn5250

Hello,

I tried to add some controls to my 5250 panels. It works pretty well but sometimes the AWT-EventQueue throws an ArrayIndexOutOfBoundsException after returning to a panel without controls:

Exception in thread "AWT-EventQueue-0" java.lang.ArrayIndexOutOfBoundsException: No such child: 1

Some code of the PanelHandler:


@Override
protected synchronized void start()
{
//....

XI5250Field f = getEmulator().getPrevFieldFromPos(dIndex, row);

if (checkField(f, 11))
{
JKalenderButton kalenderButton = new JKalenderButton();
new XI5250FieldConnection(this, f, kalenderButton, 0, 0, 3, 1);
komponenten.add(kalenderButton);
}
}



@Override
protected synchronized void stop()
{
komponenten.clear();
}



Any suggestions to avoid that the exception will be thrown?

Thanks
