This means that it will try to execute the logic in a asynchronous job. When it fails it will retry 2 times and then the job will be in a failed state and the process state will be in step 4. You can also implement error handling in the logic of step 4 and handle the error there or create a BpmnError that you can catch in an error boundary event.</SPAN><BR /><BR /><SPAN>Best regards,</SPAN></BODY></HTML> Thu, 16 May 2013 12:43:27 GMT https://connect.hyland.com/t5/alfresco-archive/everything-is-reverted-on-error/m-p/136460#M95709 trademak 2013-05-16T12:43:27Z
