Most likely, you are using a POA with the system id policy, meaning
that the object ids often contain embedded nulls. Section 1.39 of the
C++ mapping says

  "If conversion of an ObjectId to a string would result in illegal
   characters in the string (such as NUL), ObjectId_to_string throws
   the CORBA::BAD_PARAM exception."

You should only use ObjectId_to_string with user id POAs, and make
sure you use ObjectIds without embedded nulls.

Since you don't catch BAD_PARAM within your preinvoke()
implementation, the exception is propagated to the client.

Cheers,

Duncan.
