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 cal
l
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
