No, actually *YOU* are missing the point! Several people have tried to explain how this works to you. So, for one last effort.... <IMPORTANT> DO *NOT* SET THE FIELDS YOU INTENT TO USE AS CHECKBOXES (booleans) TO TRUE IN THE RESET METHOD!!!!! </IMPORTANT> If you want the field to be true when the page is rendered, set it to true from your action class, NOT in the reset of your formbean. I hope that clears it up for you. > > > BTJ > > On Tue, 2003-06-10 at 19:22, Tor Henrik Hanken wrote: > > [EMAIL PROTECTED] > > > > | Yes, but to clarify... > > | I am showing a jsp page with values read from a database.
