Issue 15754: Apparent contradiction concerning compensation handler invocations (bpmn2-rtf)
Source:  (, )
Nature: Clarification
Severity: Significant
Summary: i) Chapter/Section  13.4.5. Page 457.  It says:
“Triggering compensation for the Multi-Instance Sub-Process individually triggers compensation for all instances within the current scope. If compensation  is specified via a boundary compensation handler, this boundary compensation handler also is invoked once for each instance of the Multi-Instance Sub-Process in the current scope.”


ii) Chapter/Section  13.4.5. Page 458.  It says:
“In case the Activity is a multi-instance or loop, the Compensation Activity is triggered only once, too, and thus has to compensate the effects of all instances.”


COMMENTS:


It seems there is a contradiction between (i) and (ii). 
    - In (i) there are as many invocations as instances are.
    - In (ii) there is only one invocation for many instances.


SUGGESTIONS:

Clarify whether there is a contradiction or not.
