Insert is called instead of Update when merge() with complex IDs
Hello!
I need some help in the following situation - completely stuck with it :(
Can you please point me in some direction? Anyway, thanks in advance!
OpenJPA version is 2.0.0-M3.
So, I have three entities:
Prognosis contains many PrognosisEntry, and PrognosisEntry references
some Stock. So, it's a many-to-many for Prognosis and Stock, having some
additional data at PrognosisEntry join table. Fields:
Stock:
index (PK)
length
Prognosis:
station (PK)
type (PK)
PrognosisEntry:
prognosis.station (FK, PK)
prognosis.type (FK, PK)
stock.index (FK, PK)
localState
timestamp
Relationship between Prognosis and PrognosisEntry is bidirectional (I
really need Prognosis.getEntries() method). All IDs are taken from the
real world and not generated because this data comes from the backend in
XML and then deserialized using JAXB (annotations are removed from the
sources below to simplify it). Then I do merge() and expect the data in
the DB to be updated with the fresh one. When I call merge() for the 1st
time (against the empty DB), all the necessary INSERTs are done. But
when called for the 2nd time with the same data (I expect no changes to
the DB), the exception is thrown because of the duplicate primary keys.
Unexpectedly, it does INSERT instead of UPDATE in this case. The problem
is seems to be with the PrognosisEntry-Stock relationship, because when
I remove it (replacing reference to Stock in the PrognosisEntry with
some dummy ID field) it starts working as expected (calls UPDATE).
Exception and logs are given after the sources below.

This is a bug in openjpa. JIRA-1371 is open to address this problem.

Hello!
Neither of those, I just execute the program twice. So, it's not about
the managed / detached entities.

Re: Insert is called instead of Update when merge() with complex
IDs
Posted by Constantine Kulak <co...@mail.by>.
Hello!
Neither of those, I just execute the program twice. So, it's not about
the managed / detached entities.

Re: Insert is called instead of Update when merge() with complex IDs
Posted by Fay Wang <fy...@yahoo.com>.
The em.merge will return the merged entity.
EntityA mergedEntity = em.merge(newEntity);
During your second merge call, did you call
em.merge(mergedEntity)
or
em.merge(newEntity)?

Subject: Insert is called instead of Update when merge() with complex IDs
Hello!
I need some help in the following situation - completely stuck with it :(
Can you please point me in some direction? Anyway, thanks in advance!
OpenJPA version is 2.0.0-M3.
So, I have three entities:
Prognosis contains many PrognosisEntry, and PrognosisEntry references some Stock. So, it's a many-to-many for Prognosis and Stock, having some additional data at PrognosisEntry join table. Fields:
Stock:
index (PK)
length
Prognosis:
station (PK)
type (PK)
PrognosisEntry:
prognosis.station (FK, PK)
prognosis.type (FK, PK)
stock.index (FK, PK)
localState
timestamp
Relationship between Prognosis and PrognosisEntry is bidirectional (I really need Prognosis.getEntries() method). All IDs are taken from the real world and not generated because this data comes from the backend in XML and then deserialized using JAXB (annotations are removed from the sources below to simplify it). Then I do merge() and expect the data in the DB to be updated with the fresh one. When I call merge() for the 1st time (against the empty DB), all the necessary INSERTs are done. But when called for the 2nd time with the same data (I expect no changes to the DB), the exception is thrown because of the duplicate primary keys. Unexpectedly, it does INSERT instead of UPDATE in this case. The problem is seems to be with the PrognosisEntry-Stock relationship, because when I remove it (replacing reference to Stock in the PrognosisEntry with some dummy ID field) it starts working as expected (calls UPDATE). Exception and logs are given after the
sources below.
