Hi all,

I tried to make it to work, but after 3 days digging in the code, I cannot figure out why the POS session cannot be closed.

Here is the error I got each time :

OpenERP v7.0 on Debian.

I created 8 companies, 8 POS , 8 shops, 8 POS managers, Using currency = EU

Another time, I got this error :

I also tried to close the sessions as Admin, but nothing changed I Googled a lot but found nothing relevant.

Could somebody help me, please ?
