Notes
(0008678) twaller (manager) 2010-07-28 17:21	Unpredictable behavior. NPE when saving graph with COMPILED added: An exception stack trace is not available.

(0008679) twaller (manager) 2010-07-28 17:24	Warning remains on Reformat after removing COMPILED.

(0008680) twaller (manager) 2010-07-28 17:28	NPE-s are quite unpredictable. Now it does not happen.

(0008686) mzatopek (developer) 2010-07-28 18:10	It is really hard to reproduce - still without success.

(0008720) pnajvar (administrator) 2010-07-29 16:35	Hard to reproduce
