On the Add User Form, the delete button appears after an unsuccessful Save. Subsequent Delete result in exception (which is correct). the re-display of the Delete button is not correct.

My workflow is
1- Add user
2- Enter a Username
3- Click Save
4- Click Delete (because this button appears although nothing has been saved in
the DB)
5- Get Error page:

Yikes!
