Hello, I have found that even if you changed the requiredlock param in the sysconfig, the lock is made when you change the owner. It is the second bug I found about the lock function. a) bulk action : always lock the tickets, no requiredlock param available in the sysconfig b) changing of owner : always lock the ticket even if you change the requiredlock in the sysconfig Any feedback welcome as we are now in production and it is very annoying for the users Many thanks Greetings Philippe Martignier Communications Division Customer Service Section Email : Philippe.Martignier@wipo.intmailto:Philippe.Martignier@wipo.int Phone : 00 41 022 338 72 36 Building : GB II Office : 0,3 World Intellectual Property Organization Disclaimer: This electronic message may contain privileged, confidential and copyright protected information.
