Hi

I am getting following exception in my jsp.

Servlet.service() for servlet action threw exception
java.lang.IllegalArgumentException: Null property value for 'locationKey'

I get this exception when I click "save" button on my jsp. locationKey itself is an object of class "LocationKey" and a member of class "Location".

this is how I pass it to jsp

<html:hidden name="addressMaintenanceForm" property="location.locationKey" />
<html:hidden name="addressMaintenanceForm" property="location.locationKey.phoneNumber.number" />
<html:hidden name="addressMaintenanceForm" property="location.locationKey.phoneNumber.exchange" />
<html:hidden name="addressMaintenanceForm" property="location.locationKey.phoneNumber.areaCode" />
<html:hidden name="addressMaintenanceForm" property="location.locationKey.phoneNumber.extension" />

phoneNumber is an object and member of LocationKey and then phoneNumber has strings "number", exchange, areaCode and extension.

Can anyone please help.
Thanks
