Instantiating a Message
|

|
| How can you instantiate a Message in an Assignment Shape?
I know that you can perform a Transform (with a Transform
Shape), to move the contents from one message type to
another....
I also know that you can you can assign one Message to
another of the same type (in an Assignment Shape)....
but how do I take a Message declared in the Orchestration
Viewer and instantiate it in an Assignment Shape, so that
I can set it's promoted/distinguished properties
individually.
Thank-you

"You construct a message any time that you introduce a message into your
orchestration, either by receiving it or by assigning values to a message
variable. Any message that you construct must have a message type, so that
the runtime engine has a complete description of the object that it is
working with. The multi-part message type can be user-defined, it can be a
..NET class, or it can be a schema. You can construct messages in various
ways: you can invoke a .NET class to create a message, assign one message to
another, or use a transform to map certain values within a message to values
within another message. Messages are also constructed by a receive action or
when your orchestration accepts a message as a parameter."
So in your case, if you are not using a map or assigning the new message
from an existing message, then you need to use a helper class.
