IllegalArgumentException

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
 
It is sorta covered in the JavaRanch Style Guide.
