Name can't be blank error under parameter tab, on creating a hostgroup with activation-key

Description of problem:
I was trying to create a hostgroup and associated activation_key. But when I submitted the form, UI raises error under 'Parameters' tab. Name can't be blank. I believe activation_key param should auto set.
