Null Object reference question
|

| Hi All,
I have an orchestration which accepts one type of message in, then generates
a secondary message based on a value in the original message. The problem I'm
running into is I am getting a Null Object reference when trying to assign
the value of the originating message to my new one even though I know it
exists. (I've even validated in HAT that the value is being set). It's
defined as a Distinguished Field and a Promoted Property in the Property
Schema. I'm not sure what else I am supposed to do here.

| Hopw are you trying to assign the value from one message to another? Can you show us some code?

| Sure Code is like:
ApprovalRejection.ApprovalPart.Comment = 1;
ApprovalRejection.ApprovalPart.Date = System.DateTime.Now;
ApprovalRejection.ApprovalPart.ReplyStatus = "y";
ApprovalRejection.ApprovalPart.UserName = "Person";
ApprovalRejection.ApprovalPart.WorkflowNB = LaunchMessage.WorkflowNB;
All of the statements leading up to the last one work just fine. The
LaunchMessage is the type of the activation port receive.

| The WorkflowNB field on one of your messages is likely missing. If you have
validated that it is present in the inbound message, then it is likely that
the target message has not had this element created yet. How did you
initialize the ApprovalRejection message? Message Assignment? Map? Make
sure if you are mapping, that you create the element that is a distinguished
field.

| Actually I'm instantiating it from a C# object in my orchestration. It's
marked up as a DistinguishedFieldAttribute() and a PropertyAttribute(). Is
there anything special you have to do to include both of those markups or
just put them one after another?
