Sandro Martini commented on PIVOT-938:
--------------------------------------
Roger, is it ok to mark this as resolved now ?
This is the last bug with High Priority for the 2.0.4, so after this we could
see what of others (Low Priority) should be fixed, and finally start the
process to freeze code base for the next release ...
Thanks, Bye.

> 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?
