Hi I can't reproduce the bug.

I assume it's this line?

r.setPath(slice.getPath(), slice.getRegion());

This happened to me in piegraph and bargraph when i rapidly clicked on a loading page. I'm not quite sure why it happens but maybe it's because you can do something like call setthickness which invalidates and calls on draw before setslices can necessarily be called and the regions set. In any case adding a

if (r != null) solved it without negative consequence.

Adding if (slice.getPath() != null && slice.getRegion() != null) is okay for me now.

[Chayoung You]

Region and Path of PieSlice are final now.
