Entity data missing in enhanced mode
Hi,
I'm using OpenJPA 1.2.2 under JavaEE JPA project in Eclipse Galileo.
After adding Bytecode enhancement, named query returns only partial data.
Persisted object looks fine, has all fields filled with proper data.
But if i search for that object with named query or with
EntityManagers.find,
returned entity has 0 value in ID field, and the other fields are empty too,
except String fields.
I need all field's data from entity, for some post processing purposes.
Can anybody help, how to retrive whole data?
thanks

Wich OpenJPA version you used? I tried 1.2.2 and 1.2.3.
I am newbie on JAVA and OpenJPA too.
Can some system misconfiguration cause something like that?

Hmm, I'm still not sure what the problem is that you are reporting. I ran
your same test on HSQLDB and it worked fine for me. Sounds like I still may
be missing something?

Yes, the data is properly persisted.
I have SQL trace turned on, no errors.
I have only one strange debug message: "No cache marshaller found for id
org.apache.openjpa.conf.MetaDataCacheMaintenance."
Log is attached.
propertiesMap.put("openjpa.Log", "SQL=trace");

Your test worked fine for me on MySQL.
Did you check the database to see if the data is properly persisted? You
could try enabling SQL trace to see if that gives us any other clues:
propertiesMap.put("openjpa.Log", "SQL=trace");
Are there any warnings or other errors logged?

Thanks for quick reply.
I attached one of the Entities, and unit test.

Can you post some more information? A small unit test would be nice... but a
nice place to start would be by posting the given Entity.

Not sure if this is your issue but when I used lazy loading I had similar
issues. I removed the lazy loading and the issue went away.

Hi,

After adding Bytecode enhancement, named query returns only partial data.
Persisted object looks fine, has all fields filled with proper data.
But if i search for that object with named query or with

returned entity has 0 value in ID field, and the other fields are empty too,
except String fields.
I need all field's data from entity, for some post processing purposes.
Can anybody help, how to retrive whole data?
thanks

Finally, the problem sold with swapping from Eclipse Byte code Enhancer to
ANT based.
Thank you!

How are you enhancing the code in Eclipse? ANT script,
openjpa-maven-plugin or our Eclipse plugin?
