[omniORB] Problem with struct parameters

[Piet van Oostrum]

I have a problem with a struct parameter in omniORBpy. It looks similar
to a problem that appeared on this list 2 weeks ago ("Caught an
unexpected Python exception during up-call") but the situation is quite
different. 

I am using omniORB 4.1.3 and omniORBpy-3.3 on MacOS X 10.4 with Python
version 2.6.

I have the following idl:

------------------------------------------------------------------------
module Test {

	struct hist {
		long lower;	    
		long higher;	
	};

	interface Try {
		void meth (out hist h);
	};
};
------------------------------------------------------------------------

The server implementation of the method is:

------------------------------------------------------------------------
    def meth():
        return hist(1, 10)
------------------------------------------------------------------------
because out parameters are implemented as results.

the client code is:

------------------------------------------------------------------------
print server.meth()
------------------------------------------------------------------------

I get an exception:
------------------------------------------------------------------------
omniORB: Caught an unexpected Python exception during up-call.
TypeError: meth() takes no arguments (1 given)
Traceback (most recent call last):
  File "client.py", line 30, in <module>
    print server.meth()
  File "/Users/piet/colleges/GOB/examples/Corba/TestStructOut/strout_idl.py", line 61, in meth
    return _omnipy.invoke(self, "meth", _0_Test.Try._d_meth, args)
omniORB.CORBA.UNKNOWN: CORBA.UNKNOWN(omniORB.UNKNOWN_PythonException, CORBA.COMPLETED_MAYBE)
------------------------------------------------------------------------

Where does this argument come from? It is not in my client code. Also if
I change the method in the IDL to return the struct instead of using an
out parameter it gives the same error.

Am I doing something wrong? Is this a bug? Or is omniorbpy incompatible
with python 2.6?
