Re: [wsbpel] Issue - R27 - Faults and Parallelism in TerminationHandlers

Does this need to be generalized to not just parallel constructs?  Do
we ever say, for instance, that a fault reaching a FCT-Handler MUST
terminate all running activities in the termination handler?  I can't
find any such thing, but it seems "obvious" to me that we should have
said it.  

That would take care of your cases, too, wouldn't it?

  Issue - R27 - Faults and Parallelism in Termination Handlers
  Status: received

  Date added: 30 Oct 2006

  Date submitted: 27 October 2006

  Submitter: Dieter
Koenig

  Description: Consider the following examples of parallelism
inside of
termination handlers.
  
Example 1. Assume that a custom termination handler contains a
parallel
forEach activity or a flow activity. In either case, assume that
multiple concurrent branches are active. If one branch faults, the
specification does not tell whether the other branches are allowed to
complete or terminated.
  

  
Example 2. Assume that a default termination handler that
compensates a
compensation handler instance group. If one compensation handler
instance faults, the specification does not tell whether the other
compensation handler instances are allowed to complete or terminated.

  Submitter's proposal: Add the following to the end of section
12.6.:
  

  "If a custom termination handler contains parallel
activities and one of
these activities propagates a fault then all concurrent activities in
the termination handler MUST be terminated. Likewise, if a default
termination handler compensates a compensation handler instance group
and one of the compensation handler instances propagates a fault then
the other compensation handler instances of the compensation handler
instance group MUST be terminated."
