Vitaliy Tkachenko commented on ODE-1066:
----------------------------------------
2) For compensating a specific inner scope there is a specific activity
<compensateScope target="scope-name" />.
<compensate /> is to execute all immediately enclosed compensation handlers.
Henceforth the proposed patch ODE-1066-CompensateGenerator.patch is unnecessary.
Sathwik, this fix is for the BPEL 1 not 2 which uses the same "compensate"
activity with the "scope" attribute instead of the "compensateScope" with the
"target" attribute used in the BPEL 2.

> Compensation doesn't work appropriately, there is no guarantee that it will
> be processed on execution. It doesn't matter which BPEL version is used
> either 1.1 or 2.0 and which method is used to provide the compensation
> (either "compensate" or "compensateScope").
> If there are several scopes to compensate the most big chance to work out its
> compensation handler has the last scope - it fails rarely but scopes defined
> prior to the last scope have much bigger chances to fail. When compensation
> fails nothing is seen in the log, it just doesn't work.
> Attaching the FlightReservationProcess application to reproduce the bug.
> Specify "all" in the input to execute compensation for all scopes, call it
> many times and check how scopes are compensated. Each result 4, 5, 6 must
> contain "1" if the corresponding scope "car", "hotel" , "asbstract" has been
> compensated. But in reality the most big probability "abstract" scope has to
> include "1", it fails having the "0" pretty rarely. But other scopes "car"
> and "hotel" fail oftenly, only in rare cases they contain "1" as being
> compensated. You can also play including "car", "hotel", "abs" instead of all
> to compensate only specified scopes. E.g. use "car hotel" in the input to
> compensate these 2 scopes only.
