Hi Patric,
I wonder if you are hitting this problem:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=365623
Any chance you could try a more recent version (nightly build)
2.3.3 or 2.4?

Cheers,

Hello,
I am facing a strange issue in EclipseLink 2.1.3 at a customer
installation.
Occasionally (once a day on an average), it seems that EclipseLink
misses an
@Embedded object inside a newly persisted entity
and does not insert its values.
The Insert fails because some of these columns (of the embedded
object) are
defined as mandatory (db constraint). If this would not be the
case, a data loss would be the consequence.
Have a look at the log at level FINEST (during commit/flush):
(anonymized)
execute_query, UpdateObjectQuery(Table1Class (some parts left
out...),
recordInfo=CRecordInfo[colA=A, colB=C, colC=102283, colD=Wed Dec
28 11:43:33 CET
2011])
execute_query,
InsertObjectQuery(Table2Class[CompositePK=pk[col1=2, col2=6633],
col3=2151225, col4=FLAG, col5=N, recordInfo=CRecordInfo[colA=A,
colB=C,
colC=102283, colD=Wed Dec 28 11:43:33 CET 2011])
begin_batch_statements
UPDATE TABLE_1 (COL1, COL2, COLD, COLC, COL3) VALUES (?,?,?,?,?)
bind => [N, 2, 2011-12-28 11:43:33.804, 102283, 6633]
end_batch_statements
begin_batch_statements
INSERT INTO TABLE_2 (COL3, COL5, COL4, COL2, COL1) VALUES (?, ?,
?, ?, ?) <---
CRecordInfo Cols are missing!
bind => [2151225, N, FLAG, 2, 6633]
end_batch_statements
Local Exception Stack:
Exception [EclipseLink-4002] (Eclipse Persistence Services -
2.1.3.v20110304-r9073):
org.eclipse.persistence.exceptions.DatabaseException
Internal Exception: java.sql.BatchUpdateException: ORA-01400:
cannot insert NULL
into ("PRODUCT"."TABLE_2"."COLC")
Error Code: 1400
The problem seems to be unrelated to specific entities/tables, it
happens with
any kind of entities (all of them contain the same Embedded
entity)
Maybe it related with Batch Writing, but that is just a guess.
Database is Oracle 10.2.
The customer is not able to reproduce it - but it happens from
time to time more or less regularly.
I was also not able to reproduce this in any other environment.
Why doesn't EclipseLink insert the columns of the embedded
object (colA,colB ...)? The embedded object and its values do
clearly exist
(which you can see in line 2 of the log while printing the
InsertObjectQuery).
Another embedded object of the same type (CRecordInfo) is
successfully
processed in the UpdateQuery right before the errornous insert, as
you can see in the log, too.
Any help is appreciated. Thank you in advance.
Best regards,
Patric
