Not sure if it's working as designed but this needs to change:
When you create a consumer and go to its configuration page and hit cancel, I see that consumer in the list which is fine because you can re-configure it again but I am not able to destroy it. I get
Couldn't deregisterConsumer with id 'cons1' Cause: Cannot deregister producer 'cons1' as it's not registered
where 'cons1' is the name I gave.
