Hi all,
I am doing a survey on BPEL's compensation instances group and I found
some strange nature which is not specific in the BPEL specification 2.0, I
am not sure if it is normal or not in all BPEL server, or anyone has the
practical example to support the strange nature?
As the following program, a while loop count x from 0 to 5, it contains a
scope, the scope increase X by 1, the compensation of the scope decrease X
by 1.
the strange is, if a throw inside the while loop is called(e.g. throw_1),
the last compensation instance is executed. X will finally be 2. on the
other hand, if a throw outside the while loop is called(throw_2), all
compensation instances are invoked and X will finally be 0. It is strange
that the throw_1 can not call all the compenstion instances...Please
comment. Thanks!
X=0
While X < 5
{ A ? C , F } where A has activity X= X + 1, C is compensation X=X
-1, F is the fault handler.
if x >2 then (throw_1-> compensate)
loop
(throw_2 -> compensate)
