Used unsaved-value="any" for <composite-id>, Getting exception Object references an unsaved transient instance - save the transient instance before flushing, even though record exist in the DB
------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Key: HHH-5170
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5170
Project: Hibernate Core
Issue Type: Bug
Components: core
Affects Versions: 3.2.3
Environment: DB2-z Series, Weblogic 10.3 App Server.
Reporter: Deepesh Seetharaman
Attachments: EventService.hbm.xml, State.hbm.xml, test.zip
I have attached the following files.
i)EventService.hbm.xml
ii)State.hbm.xml
While I am trying to persist, EventService, by setting the State object, with only its id fields its giving the folloiwing exception.
org.springframework.dao.InvalidDataAccessApiUsageException: object references an unsaved transient instance - save the transient instance before flushing: com.fareis.las.css.sys.rf.domain.State; nested exception is org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.fareis.las.css.sys.rf.domain.State
Caused by: org.hibernate.TransientObjectException: object references an unsaved transient instance - save the transient instance before flushing: com.fareis.las.css.sys.rf.domain.State

I am creating the instance like this.
EventService service = new EventService();
State state = new State();
StateId id = new StateId();
id.setStateCode("DAS");
Country country = new Country();
country.setCountryCode("US");
id.setCountryCode(country);
state.setId(id);
service.setBillingId(10);
service.setStatusCode("A");
service.setState(state);
service.setClientBillingEventKey(clientBillingEvent);
service.setLastUpdateSourceId("TEST");
service.setLastUpdateTimestamp(new java.util.Date());
service.setLastUpdateUserId("sdeepesh");
service.setCorrDate(new Date(System.currentTimeMillis()));
service.set ... other not-null fields.
State.hbm.xml's <id property is using unsaved-value="any", if you remove that attribute everything works fine, but it will fire a SELECT SQL to the STATE table, to verify the integrity of the <id>.
We had explicitly mentioned the unsaved-value="any", in order to prevent the SELECT being fired.
Ironicall I found out that when you make unsaved-value="none", everything works perfectly, but then unsaved-value is having this unpredictable behaviour about it's value.
We are using unsaved-value attribute for all <id, <composite-id which has <generated-class as "assigned", the values are like below
<id unsaved-value="id_value" - id is a String
<id unsaved-value="none" - id is a Integer
<composite-id unsaved-value="any"
For composite-id everywhere we used, unsaved-value="any", the only contradicting place where we found is with State.hbm.xml
If possible please provide some guidelines as to use the "unsaved-value", we mainly used that to prevent the SELECT SQLs from executing before performing INSERT.
Also while debugging through the hibernate code, I found that it is performing dirtyCheck for EventService instance, where it compares loaded value and current value.
I found that loaded value was having State object as null.
Please provde your comments.
I have also attached the test cases, but you wont able to run it, due to compilation problems,
testAddEvent is the one which is failing
