Hi Erik, Andy,
I have written a test case checking single field identity. For this
purpose, I created new PC classes, new jdo files, new orm files, and I
extended the schema for application identity. When I run the test case,
I get a JDOFatalInternalException from JPOX (see below). Currently, I
run build jpox-20050617.022105.jar.
The exception is thrown when a PC instance is made persistent. I cannot
find an error in the meta data. So, please have a look at the attached
files. I attached the Java file of the PC class and the meta data files.
Is there anything wrong?
Regards,
Michael
