This is happening because when you click submit and go to validate(...) in your form class a new form is created and populated with the request parameters from the JSP page. So if you don't have postDate as a hidden field or put the form in session the value will be lost. Ted posted a message on this topic not too long ago about how to handle this situation.

Well, I did a test and bean:write displays the date the first time thru, but then displays nothing when I return to the page to display validation errors? Why would this value be getting cleared in my form? I null out all my fields in the reset method including this 'postDate' property. Any ideas? -----Original Message----- From: Keith Bacon [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 19, 2001 7:15 AM To: Struts Users Mailing List Subject: RE: Problem with bean:define? are you saying your jsp is getting null pointer excp in setAttribute() in the <bean:define tag? does this work? <bean:write name="editRegForm" property="postDate" /> Keith.
