Issue 16904: Is compensation allways triggered automatically upon uncaught errors? (bpmn2-rtf)
Source: Camunda Services GmbH (Mr. Falko Menge, falko.menge(at)camunda.com)
Nature: Clarification
Severity: Significant
Summary: Page 180 (PDF 210) states:
'Note that other mechanisms for interrupting a Transaction Sub-Process will not cause compensation (e.g., Error, Timer, and anything for a non-Transaction Activity).'


Whereas page 305 (PDF 335) states:
'If no error Event Sub-Process is specified for a particular Sub-Process and a particular error, the default behavior is to  automatically call compensation for all contained Activities of that Sub-Process if that error is thrown, ensuring the behavior for auditing and monitoring.'


These statements seem contradicting to me and  therefore I'd like to get a clarification on the following questions:


1. Is compensation allways triggered automatically upon uncaught errors?
2. Is there a difference between compensation of a Transaction Sub-Process and any other Sub-Process?
