Are you parsing the dates using <fmt:parseDate>? If so, then according to the spec, the if the input value is null or "" the variable specifed by var will be removed. You could then use the empty operator to check for a null value. Hope this helps.

I need to set the value of a date field to null. How can I create an object that equates to null? The JSTL spec for dateParam says that if the value equates to null the column will be set to null but i have not figured out how to create a null object in JSP. Any ideas?? Thanks Anand Narayan -----Original Message----- From: Nic Werner [mailto:[EMAIL PROTECTED] Sent: Wednesday, July 30, 2003 1:27 PM To: Tag Libraries Users List Subject: Handling null dates Greetings, I have a form that has a lot of date fields, they represent dates someone attempted to take a test. There are multiple sets of these for each attempt they have taken, but I run into trouble if there is only one test attempt, meaning there are blank dates for the other attempts. Is there any way I can have the form send over the blank values and JSTL will just update the database with these blank values? I've tried to detect if the date is empty and just set the variable to be updated to be blank with <c:set value="" var="datetaken"/> but I get invalid column type.
