But than doesn't it defeat the purpose of the validate() method in the form
and complicates the code?
Wouldn't it be better to have some sort of <htlm:label ...> or something to
allow to show some form fields not as input field but as simple text.
This problem must have been discussed already. If you have any reference
discussions I will be happy to have a look.
