[omniORB] CORBA.TypeCode() on enum fails in omniorbpy

It's kind-of by design. The Python language mapping says:

  For user-defined types, a function CORBA.TypeCode can be used to
  create the type codes. This function expects the repository ID. If
  creation of the type code fails, CORBA.TypeCode raises a system
  exception. The repository ID of a type can be obtained with the
  function CORBA.id, passing the object representing the type. Such an
  object shall be available for every IDL type with a <scoped_name>,
  including names that are not otherwise mapped to a Python construct
  (such as type aliases). If an invalid object is passed to CORBA.id, a
  BAD_PARAM system exception is raised.

so you can get the TypeCode for your enum with:

  tc = CORBA.TypeCode(CORBA.id(Test.TestEnum))

It's an omniORB extension that you can use CORBA.TypeCode() directly
with other generated classes like those for structs and interfaces. I'll
make it work for enums too.

Another omniORB extension is that the IDL compiler helpfully makes a
TypeCode for you, so you can get the TypeCode you want just like this:

  tc = Test._tc_TestEnum

Cheers,

Duncan.
