[omniORB] OrbixWeb server answers OBJECT_NOT_EXIST while invoking

[Rebecca.A.Sanford@gd-is.com]

FYI: I'm having the same problem when using Orbix 2.3c03 (patched version)
and omniORB 2.7.0 on WindowsNT...

I was just about to spend some lab time trying to debug the SAME problem.
You guys must be psychic!  Thanks for the preemptive help!!

That's Right Sai-Lai!

That did it, I commented out two rows and recomplied OmniORB and now it
works.
I'll have a chat with the OrbixWeb guys.

Just another question: is it safe to run with these binaries without the
asserts as a temporary solution?
