Use Of Unconstructed Message Error
|

| This should be a simple thing to fix but I have not been able to figure it
out. I have a very simple orchestration, at this point, which just takes in
a message transforms it to the same message type then sends. We are just
manipulating some of the data within the map so the in and out schemas are
the same. I continue to get the "use of unconstructed message" error when I
attempt to build it. I have created the message in the orchestration view.
The receive port uses File Transport. The Receive Shape specifies the
message. I have a construct shape with a transform. The "Messages
Constructed" in the construct shape specifes the message. The transform
specifies the map and schemas. I do not know what else to do. I have looked
at the article Matt Meleski's .Net Blog - The ABC's of .NET
ASP.NET/ADO.NET/Biztalk 2004/C#
Constructing BizTalk 2004 XML Messages (In an Orchestration) - Choices
and it states that a port or map should take care of this error. I have
both. I am at a loss. Are there any settings that I am missing? I compared
this to the tutorial orchestrations that I have gone through and do not see
what I have missed. Any suggestions are appreciated. It seems like this
should be so simple.

| Have you accidently stated that you construct bother the new and original message in the ConstructMessage shape? You only need to specify the resulting message.

| That was it. Thank you for the help. I am still trying to pickup the basics
here. I guess that means that I have to create two Messages in the
Orchestration View even though the in and the out are using the exact same
schema?

| Absolutely. Even though the messages are of the same type they are in fact two different messages (as far as BizTalk is concerned all messages are immutable once they enter the messagebox). So you use an existing message as input and create a new message
of the same type.
