I am trying to unmarshal an object part of which is a date. This date is
not always set in the DB,
so at times it could be null. When Castor tries to unmarshal it when it is
null, I get a NullPointerException
and then
java.lang.NullPointerException

>>>---- End Exception ----<<<
My object declares a property
(using java.util.Date)
private Date ExpireDate;
And my mapping file looks like:
<field name="ExpireDate" type="java.util.Date" direct="false">
<bind-xml name="ExpireDate" node="element"/>
</field>
Can anyone give me their thoughts of whether it should be able to handle a
null value,
or a way for me to handle it myself.
Thanks
