Hi,
to cut things short, can I ask you somthing ? Can you please - for the
time being - switch to using the generated descriptor classes, as I am
100% sure that things should work out of the box.
In other words, drop generation of the mapping file, re-enable
generation of the descriptor classes, and you should be flying. As you
compile and package your applications, don't forget to include the
.castor.cdr files as generated during code generation.
Can you please try that ?
