Added spry validation to all the backend datassist generated insert and update pages.
Only had a problem with the password field on the user update page. Tried to change the spry validation from a required text field to a password type validation using the same parameters as the password field on the registration page.
This would accept a valid password but would blank the password field on submit in the database.
It works ok when I reverted back to a required text validation field but obviously doesnt check for a valid password.
