I'm creating process with 14 actors. But in CE I see only 10 actors. Is this CE restriction?
I'm not aware about any restriction on the number of actors. Where did you see it?
When we try to intall process in Bonita CE we must to select the entities (users, groups, roles, memberships) to map to the actors. So we can see only 10 actors.
I'm pretty sure you can create as much as you want.
