RE: OJB and the X-Files... :)

Hi Armin,

I've been able to successfully recreate this error with the
InheritanceMultipleTableTest Test cases. Again I'm using the broker API and
the latest code from SVN OJB_1_0_RELEASE.

I added the code below to the test and like I described with my project when
org.apache.ojb.broker.accesslayer.sql.SqlGeneratorDefaultImpl.LogLevel is
set to WARN it does not return the right class and when I set
org.apache.ojb.broker.accesslayer.sql.SqlGeneratorDefaultImpl.LogLevel to
DEBUG it returns the right class.

Employee employee = new Employee();
employee.setId(newEx1.getId());
employee.setId_2(newEx1.getId_2());
            
Identity employee_oid = broker.serviceIdentity().buildIdentity(employee);
Employee employee1 = (Employee) broker.getObjectByIdentity(employee_oid);
            
log.debug("Employee: " + employee1);
            
assertEquals(Executive.class.getName(), employee1.getClass().getName()); 

Please note that when I test this with the latest release of OJB,
db-ojb-1.0.4.jar, this works fine. This indicates one of two things. Either
I'm downloading and building the code from OJB_1_0_RELEASE incorrectly or a
bug was introduced into the OJB_1_0_RELEASE code. Please look into this and
advise me further, thank you.

Regards,
Chris

Now I'm stumped. If it is reproducible in a separate test, please add a 
issue in JIRA (with detailed pseudo code or a test case).

It would be really helpful if you can reproduce this behavior with a 
simple test case.

Hi Chris,

it was fixed (by Jakob) in OJB_1_0_RELEASE branch and will be included 
in OJB 1.0.5.

Thanks Armin,

Please let us know when it is fixed. When is OJB 1.0.5 scheduled to be

Hi Chris,

thanks much for detailed description. Yes, I can reproduce this issue 
with latest from OJB_1_0_RELEASE branch too (I checked in a test case: 
InheritanceMultipleTableTest#testLookupByIdentity_2()).
You are right it's a bug. We will fix this ASAP.

Re: OJB and the X-Files... :)

Posted by Armin Waibel <ar...@apache.org>.
Hi Chris,

thanks much for detailed description. Yes, I can reproduce this issue 
with latest from OJB_1_0_RELEASE branch too (I checked in a test case: 
InheritanceMultipleTableTest#testLookupByIdentity_2()).
You are right it's a bug. We will fix this ASAP.

regards,
Armin
