The problem comes from the timestamps. We had seen this bug before with
GIR. The reason being that inserts that do not contain the TIMESTAMP
field will automatically insert 0000-00-00 00:00:00. I'm not sure its a
hibernate or mysql behaviour but I would guess mysql
Nevertheless, hibernate doesn't see entries with these kind of versions
as "versions" of an instance. Therefore, it crashes when trying to
save. I will look if there is such a bug logged for hibernate and if so
if they plan to fix it.
To patch this problem, I have modified the initialization scripts (sql)
of the authentication to have a default SQL for the TIMESTAMP of
2005-01-01 00:00:00. I know its not ideal but until hiberntate is
fixed, its the best I could come up with.

I just found a bug that I hadn't seen before and want to know if you
guys have noticed it.
In any application started with StartTemplate.zuml (so with the
default Logins) I get the following error when trying to add a
LoginRole to a newly created LoginGroup:
10:29:44,957 INFO [STDOUT] Caused by:

Do any of you why I am getting this? I will open a bug.
