Good Morning

I am using Hibernate 2.1.2 with Spring 1.0RC1 and SQLServer 2000.

I have a domain object HealthInsurance which has 2 attributes of type of MedicalInsurance.

The mapping has entries

-------------------------------------------------------------------
<many-to-one
name="typeOfInsuranceAtDiagnosis"
class="xx.domain.MedicalInsurance"
cascade="none"
outer-join="auto"
update="true"
insert="true"
column="INSURANCE_AT_DIAGNOSIS_CODE"
/>

<many-to-one
name="typeOfInsuranceAtEntry"
class="xx.domain.MedicalInsurance"
cascade="none"
outer-join="auto"
update="true"
insert="true"
column="INSURANCE_AT_ENTRY_CODE"
/>
-------------------------------------------------------------------


When I try to "save" a newly created HealthInsurance object with both attributes,
// START OF CODE
hi.getTypeOfInsuranceAtDiagnosis().setCode("MCARE");
hi.getTypeOfInsuranceAtEntry().setCode("MCAID");
getHibernateTemplate().save(hi);
// END OF CODE

everything works fine.

If I try to save with only one attribute ,
// START OF CODE
hi.getTypeOfInsuranceAtEntry().setCode("MCAID");
getHibernateTemplate().save(hi);
// END OF CODE

I get the following error:
// STACK TRACE

I was looking through the Reference Documentation Sec 8.8.1 but there was not much I could relate to this scenario.

Any help/pointers in solving this problem is much appreciated.

Thanks

I could save the data in the containing object by setting the update="false" in the many-to-one mappings for both attributes (contained object) in the containing object.

Now, that creates a related problem. I am unable to update these 2 attributes after I create the containing object. The call goes through but the values are not updated.

I am going through 5.1.10 but yet no success.

How are people dealing with this situation?

Thanks
Madhu
