I am trying to use the seam identity management but I am trying to change the username of the useraccount table to use email address as the username. I did not edit the useraccount table. I just feel that I can use email address as the username. However, when I do this I ran into error but when I used ordinary name everything is fine.
Can someone help me and explain what I should or can do to make this use username name. I was actually thinking may be I could use the @Email annotation in the UserAccount table or I should just used regular expression annotation at that point.
