[omniORB] BAD_TYPECODE: Java <--> Python

[entonh at gmx.de]

Here is an extract from the java implementation:

public Any getVariable(String Name) throws Exception 
{
	try 
        {
		Object[] objectArray = Server.getVariable(Name);
		org.omg.CORBA.Any aAny = orb.create_any();
                HelperJava.insertObjectArray(aAny, objectArray);
		return aAny;
	} 
        catch (Exception e) 
        {
		throw new Exception(e.getMessage());
	}
}

The message after calling getVariable by the python client sounds like:

Exception: BAD_TYPECODE ... COMPLETED YES

The idl was created before the programming started.

Cheers,
EntonH
