Javi, without the intention of slowing things down, I find it odd to do this at registration time, as the same activity can be used in different workflows with different names, so I would just do this at runtime, instead of registration. I might not have the full context if you have discussed this with the team. Registering the same activity with multiple names also looks odd to me - Blog: http://salaboy.com <http://salaboy.wordpress.com> - Github user: http://github.com/salaboy - Twitter: http://twitter.com/salaboy - Mauricio "Salaboy" Salatino -
