Hello again,

I am trying to implement a retry pattern inside a compensation shape, so
that the compensation code is retried (in a Loop) a specified number of
times. In every failed attempt at compensation, I suspend the Orchestration
using the Suspend Shape.

I am implementing the pattern as described here:
http://biztalkblogs.com/satishv278/...5/12/26/79.aspx

My problem is: I have an Atomic Shape with a compensation block.
In the compensation block, I can use the Suspend shape. However, if I add a
Long Running scope inside the compensation block, BizTalk doesn't allow me t
o
add the Suspend shape inside it.

The documentation says that "You cannot place a Suspend shape inside an
atomic transaction", but what is not working is adding it in the Long Runnin
g
Transaction.

What's wrong?

Actually, it's worse than I thought. If I have an Atomic scope with an
Exception handler, I can add the Suspend Shape to the Exception handler
freely. If, however, I add even a simple Group Shape (i.e., it's not limited
to the LR Scope shape like I assumed in my original post), I can't use the
Suspend Shape inside it!

Note that this happens in both Bts2004 Sp1 and Bts2006 beta2, so I assume
it's intentional, I just can't understand the rationale.

The way around this weird behaviour is simple, if un-elegant: create a
second orchestration with a single Suspend Shape, receiving the suspend
message as a parameter. And in the original orchestration, do a Call
Orchestration where the Suspend shape would have been. This solution seems t
o
work fine.

Thanks anyway,
João Martins
