Sequential Convoy Sample

| I have been trying to get a sequential convoy example to work.
I created a simple orchestration with only one type of message, no transformations or anything.
I start with a receive action, move onto an expression where I extract one of the distinguished fields. Then I have a loop where I check to see if the distinguished field is true.
Inside of the loop I have another receive action shape. Both receive shapes are connected to on receive port (using an XMLReceive pipeline).
Even if I drop in an xml file that has my distinguished field set to 'true', I get the message:
"The Messaging engine failed to process a message submitted by adapter:FILE Source URL:C:\Labs\BLT\ExSeqConvoy\In\*.xml. Details:Could not find a matching subscription for the message. . This error occurs if the subscribed orchestration schedule or send port has not been started, or if some of the message properties necessary for subscription evaluation have not been promoted. Please refer to Health and Activity Tracking tool for more detailed information on this failure"
I do not understand why it is saying that it cannot find a subscription. I actually created the xml document by geneerating an instance from the ..xsd document. What am I missing here?
Thanks.

| Hi Norton,
I have a working sample that I will post on my Blog today, or tomorrow.

Check it out then.
