Inheritance problem(migrate from 1.0.3 to 1.0.4)

Hi

I read http://db.apache.org/ojb/docu/guides/advanced-technique.html
and I use Mapping Inheritance Hierarchies/Table Per Subclass via Foreign
Key.
My java class are list below.
When I call PB API to store DriverDownloadLog, I got errors in ojb 1.0.4

[org.apache.ojb.broker.accesslayer.JdbcAccessImpl] ERROR:
* SQLException during execution of sql-statement:
* sql statement was 'INSERT INTO DriverDownloadLog
(id,fileTile,fileName,fileSize,driverID,UserActionLogID) VALUES
(?,?,?,?,?,?) '
* Exception message is [ORA-02291: integrity constraint (
SVTS.DRIVERDOWNLOADLOG_FK_1) violated - parent key not found
]
* Vendor error code [2291]
* SQL state code [23000=INTEGRITY CONSTRAINT VIOLATION]
* Target class is 'com.via.sv.domain.DriverDownloadLog'
* PK of the target object is [id=520]
* Source object: com.via.sv.domain.DriverDownloadLog@859367
* The root stack trace is -->
* java.sql.SQLException: ORA-02291: integrity constraint (
SVTS.DRIVERDOWNLOADLOG_FK_1) violated - parent key not found

and p6spy shows
UPDATE OJB_HL_SEQ SET MAX_KEY='520',GRAB_SIZE='1',VERSION='520' WHERE
TABLENAME = 'SEQ_UserActionLog'  AND VERSION = '519'
UPDATE OJB_HL_SEQ SET MAX_KEY='519',GRAB_SIZE='1',VERSION='519' WHERE
TABLENAME = 'SEQ_UserActionLog'  AND VERSION = '518'
INSERT INTO UserActionLog
(id,machineIP,actionName,actionDate,actionDescription,userAccount) VALUES
('519','127.0.0.1','Download Driver','2006-10-12 17:16:06.875','Download
Driver','creator')
INSERT INTO DriverDownloadLog
(id,fileTile,fileName,fileSize,driverID,UserActionLogID) VALUES ('520','Bug
Report','borg.jpg','258041','80','0')


It seems that child class can not get the parent's key.
but it works fine in ojb 1.0.3
I don't know why there are errors in 1.0.4
Is it a bug for 1.0.4 ?
Or I made something wrong ?
