I am having problems with the SendWorkflowMessage method in that it does not appear to be adding the fields " or " Where can I find these fields that are supposed to be populated when using the cdowfStrict sending method. I have found a workaround but it requires sending 2 emails to obtain the trackingid from the trackingtable of the workflowsession object in order to have a reply fire the onReceived event of the workflow.
