This is a bug in ODB. The container_statement_cache class is only
defined in the generated source file corresponding to an object
class. While this wasn't a problem before, now, with polymorphism
support, we need to reference object statements from different
classes in a hierarchy. And then this becomes a problem. Thanks
for reporting it!
I came up with a fix and prepared a test package for libodb-oracle:
I tested it with the modified polymorphism example as you described
and it works as expected. I am pretty sure it will work for your
application as well. Can you confirm this and then I will release
the official bug-fix.
