Multiple users on same point of sale broke POS

on 4/16/13, 9:30 AM 6,170 views

If I understand correctly, each POS admits only one concurrent user. That is, if I want to have two point in a department I need two POS.

But now if I have (said user_1) on main pos in a physical selling point then in the other physical selling point the systems allow me to enter in the same pos (main) with another user... and then raises an exception (TypeError in models.js, "self.get(...) is undefined") which can't be recovered from the pos interface, leaving me with a blocked terminal showing the error (but can't press any button or going back).

If my first impression is right (only one user concurrent) why allows me to enter with other user? and if not, why this error?

Any suggestions? maybe I have to fill a bug?

One user per Pos Session: it is a matter of responsibility within your company; this is an "internal control" issue. Now, you should setup 2 "selling positions" (2 shops); each one having its own opened session.

apply this patch in POS

also never try to start a new session without closing a previous session. This is a bug in POS that it cannot handle two sessions simultaneously. The above patch does not resolve the bug but prevents the system from breaking at any stage inside POS.
