This might be resolved completely in 10.2.0.4, anyone?

First make sure your environment is setup properly for OIM [...]

If you’ve just upgraded from 9i to 10g, and you are using unsupported collection return types in pipelined functions you are no longer able to compile the code due to a more restrictive 10g compiler. Your pipelined functions compiled just fine on 9i. You are unable to compile the functions with the following error message [...]
