Add lock mecanism for ticket editing

I'm using the Behaviours plugin for this.

Yes!

I had not noticed this option this plugin, but it would be even better if this option was incorporated into the core GLPI, and not have to install a plugin for that reason alone.

Thanks Javier.

You're welcome Rodrigo, i agree with you.

Find here some specifications: https://github.com/glpi-project/glpi/issues/54

The feature has been integrated in the next major GLPi release
