JIRA MULE-714 in 1.3?

Hi, I'm using the patch attached to MULE-714 for performing outbound read queries and in the snapshot version it works just fine. When I switched to 1.3 all the message properties gets lost. It seems quite natural since the code in the patch returns a new MuleMessage with the return value from the select query so it's a new instance of a message that doesn't know anything about the old properties but how could this work in the snapshot version? And how could I make this work in 1.3?
Normally I always go for snapshot version when I do projects but in this case I have to launch this at a customer in a production environment and it feels more serious to use a stable version, that's why I have to get this working with the 1.3 version.
