Problem with Loop Shape, project does not compile, help required

| Hi All,
I am experiencing some problems with the loop shape.
Here is what i am tryign to acheive:
Now i have so much working:
(Orc= orchestration)
Orc A:
Recv Req (Msg A) --- Call Orchestration (Orc B) --- Constrcut Msg(
Transform Msg B to Msg C)
--- Send Msg C
Orc B:
[---Correlated Send and Recv--]
Send Msg A --- Recv -- Msg B
[Msg A is input message parameter for Orc B]
[Msg B is output message parameter for Orc B]
Now this biztalk proj compiles fine,
Now here comes the problem, Now if i put a loop around the orchestration call
shape in Orc A,
that is:
Orc A:
Recv Req (Msg A)
|
|
V
Call Orchestration (Orc B)<----------------
| |
| |
Loop (while MsgB.result==false) -------
|
|
V
Constrcut Msg( Transform Msg B to Msg C)
|
|
V
Send Msg C
Now when i compile this project, the error i get is:
* use of unconstructed message 'MsgB' (at expression for the Loop shape)
* use of unconstructed message 'MsgB' (at the transform shape within the
Construct Msg shape)
What more shd i do to get it working??
Why does this occur??
I tried a way suggested, to constrcut the message C using message assignment and using a variable of System.Xml.XmlDocument...but it is leading to other problems like a error at runtime saying FormatExcpetion.
Why is this problem with loop, am i doing anything wrong or is it a bug with BizTalk 2004?
Plz Help me out! :|
i am pretty desperate to get it working so you can reply
me at ngmujumdar@hotmail.com
Thanks in advance
