I try to process a MRM message, which contains a CWF compound type of choice.
I'm on Win2K with CSD03.
The Message has the following structure:
EL_1 (4 Byte CHAR) - which determines what follows
CH_1 (3 Byte CHAR) or CH_2 (2 Byte CHAR) or nothing.
In MRM it is defined as
EL_1 STRING (4)
CHOICE_Elem Compound Type Choice, Type Content Closed
CH_1 STRING (3), no min or max occurs
CH_2 STRING (2), no min or max occurs

When I reference the first element in a compute node by
"InputBody"."CHOICE_Elem"."CH_1"
everything is fine; when I try to reference the second element by
"InputBody"."CHOICE_Elem"."CH_2"
I get an error message in the usertrace

2003-03-19 17:33:36.139999 726 ParserException BIP5171E: Custom Wire Format parsing error
An error occurred while parsing a Custom Wire Format message.
Current message : 'TEST_MSG'
Current element : 'CHOICE_Elem'
Path from message root : '/TEST_MSG'
Offset from start of message : 4
See following errors for more details.
2003-03-19 17:33:36.139999 726 ParserException BIP5181E: Custom Wire Format error. Message bitstream smaller than expected.
Current element '0'.
The bitstream is smaller than expected for a CWF message of this message type.

I've struggled with this problem quite some time, but cannot find the reason.
Any ideas?

Thanks,

Barbara
