The incoming message is specifying its own filtering parameter?? Can you outline the full use case more clearly please Martin i.e. when/how would this be used? Yes, exactly. Here is a sample scenario: * A message contains an order. Each order item carries a store code and a weight. * For minimizing postage cost, a custom action will compose an XPath query that points to the store code of the heaviest item in the order. * CBR will use this query to route the message to the corresponding store for process.
