In my LLBLGen project (LLBLGen 3.1, Dataadapter) there is an entity which has a field state.

Users with a specific role can only change the state into one specific state:

• Role A users can only set the state to state X
• Role B users can only set the state to state Y
• Role C users can only set the state to state ZCan I make sure this happens right using an Authoriser class on the entity? I have tried to override the CanSetFieldValue function, but it looks like I don't have a reference to the new value of the state.

Never mind, I haven't looked into the docs enough. Just use a Validator and I'm done...

This would better be handled by a Validator.
