I traced error to following piece of code:
triggerTooltipCallback = ApplicationContext.scheduleCallback(new Runnable() {
@Override
public void run() {
Point mouseLocationLocal = getMouseLocation();
componentTooltipListeners.tooltipTriggered(Component.this,
mouseLocationLocal.x, mouseLocationLocal.y);
}
}, tooltipDelay);
It seem like value returned from getMouseLocation() is null for some reason.
Unfortunately I am not able to reproduce this error. Do you have any ideas how
to avoid such problems in future?
