I am having the same problem. Every time I submit, I get a validation error: j_id4:userGroups: Validation Error: Value is not valid I am not using MyFaces, I am using JSF 1.2 reference impl. I override the equals method on the Entity, which is never getting called. I don't think the conversion logic is getting called, because the objects are not getting instantiated after submitting the form. The page is getting redisplayed with the error above, with no other valuable output. Any ideas? Thanks! View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966144#...
