Inner exception: Object reference not set to an instance of an object

[Ginny]

HI,

I have created a very simple orchestration with a construct message shape
inside a decide shape. when i run the orchestrationa and drop my file. i get
the following error mentioned below. In my decide shape i have written a
single line of code for the boolean excpression checking the value of a
distinguished field. i am actually using the biztalk 2006 tutorial 1: EAI.
Please assist.

It's must be simple...
You must use any Message for construct message shape,
for exsample:
MyMessage(MyProjectName.PropertyShema.MyIntegerDistinguichField) = 1;
But check into construct message shape properies that type
<Messages Constructed: MyMessage>
p.s.
You don't need construct received message(he was constructed automatically)

and one more reason that you don't Construct message as well befor .....
