id 'ac5v4bnnvn6YU18C0PDN461300' is not numeric for class Client - by: Segelohr

Hello everybody.

I evaluate Projeqtor for our company and installed V7.4.3 (224) on a Synology 918+
I accessed it with firefox 66.0.2 (64-Bit) and admin/admin

When I try to create any artefact (here for example a client) i loose connection
and the log entry is:

2019-04-11 10:07:49.113 ===== TRACE ===== NEW CONNECTED USER 'admin'
