Hi, I already replied to this problem through the Jira issue at
http://jira.codehaus.org/browse/CASTOR and told you that the problem is rootet in the fact that you set most of the members of HearingDetailsVO to "", which will prevent Castor from using the default mechanism of not producing elements for uninitialized members.
