CAST INTEGER to BLOB: ENCODING problem.

We encountered a problem while trying to set an integer field into an outgoing message.

The problem is the following:
We receive a message as BLOB and after having enriched the message, we have to set the length of the message at the beginning of the message.

To test the enrichment I have created a very simple message flow. The flow gets the message as BLOB and adds an integer at the beginning of the BLOB in a compute node. The integer has to be encoded in function of the destination platform witch is a Little Endian representation.

Here is the code:

DECLARE length INT 7;
-- An integer
SET OutputRoot.BLOB.BLOB = CAST(length AS BLOB ENCODING 546) || InputRoot.BLOB.BLOB;

When the message arrives on the queue, the integer is not converted into a little endian representation but Big Endian. It seems that the encoding parameter has no effect onto the casting.

If we create a message set with two fields, the first is an integer and the second is a string. The integer is correctly converted according to the MQMD encoding.

We use the WBIMB V5 CSD04
