Hi Peter, I understand that the equals in my Entity should be overridden as to prevent the default comparison of instances, but is id equality a requirement somehow? Currently, my equals does a value comparison of all fields in the Entity, save for the id, and I'm still having the same error (Value is not a valid option). I'd like to avoid comparing ids if possible. Thank you. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989243#...
