Subject Re: IdlToWsdl corba binding type tests

Hello Matteo,

I think I've tracked down the cause of the problem.

The reason this was happening was due to the way the conversion from the
Byte object to the Character object was being made.  Using a negative byte
value to create a new character resulted in the value of the character
within its range and causing a large character value.  (i.e. byte value of
resulted in a character with value 65408).  When this value was passed to
ORB, the stream checked to ensure that the value was not greater than 255
OMG range for a character is 0 to 255) and since it was, threw a

I'm going to add something to the PrimitiveHandler so that the correct
from a byte value to a character value is performed.  This should solve the
you are seeing with the failing character test.
