RDi 9.1: not getting an error list when using a custom compile command

My use of a custom compile command (apparently) breaks the error message
retrieval/insertion process.

When I compile using an IBM command (CRTBNDRPG, CRTSQLRPGI, etc.), the
error list gets pulled from EVFEVENT and the errors are inserted, all
expected behaviors.

I used a generic object create command (with *EVENTF specified) in RDi 8.5
and I'd get the errors back. But on RDi 9.0 and 9.1, and with the same
command, I'm not getting my errors back, The job log shows the results but
the error list isn't refreshed--in fact, the previous list isn't even
cleared. EVFEVENT shows the same number of records for a given compile
regardless of the compile command (my object build or the naked IBM
command).

Using Work with Compile Commands, I set up a tailored version of CRTSQLRPGI
and got errors back. The same command string in a stand-alone CL program
executed from the the list of compile commands failed to retrieve the
errors. So, it appears the compile part is okay: the object is created
when the compile is successful and the EVFEVENT member has the
warnings/errors. That leads me to think that the message retrieval
behavior is triggered by receiving a message or checking the status of an
object (message queue or data area?).

I'm stumped and would appreciate any suggestions.

Thank you!
