Validation question:not required but still needs to be validated if entered

[Shah, Shrihas \(OFT\)]

Hi :   I have a date field and it is not a required field. If somebody enters the value then It has to be valid date though. How should I do it? I have removed required flag in my validation.xml but it still says required.   My validation.xml entry looks like            <field    property="dob"                depends="date">                  <arg0 key="createAccountLevel1Form.dob"/>                      <var>                        <var-name>datePatternStrict</var-name>                        <var-value>MM/dd/yyyy</var-value>                      </var>                            </field>   I removed required flag but it still stays required.     Thanks   Shrihas.   Shrihas Shah NYS Office for Technology [EMAIL PROTECTED] Phone (518) 408-2382 Fax (518) 473-3389 (US Postal Service Regular Mail Address) State Capitol ESP, PO Box 2062 Albany, NY 12220-0062 (Parcel Post/Overnight and Interagency Mail Address) Empire State Plaza Swan St., Core 4, 1st Floor Albany, NY 12223
