Description of problem: When AuditMode for given deployment is set to NONE (vie kie-deployment-descriptor.xml), the execution of a process from this deployment is not behaving properly. Version-Release number of selected component (if applicable): BPM Suite 6.2 How reproducible: always Steps to Reproduce: 1. Model random process 2. Configure AuditMode to NONE via business-central UI 3. Deploy and run this process Actual results: When starting the process, popup window with following message is displayed: "Unexpected error encountered : null" Expected results: Process execution goes flawlessly even with AuditMode == NONE Additional info: 1st observation: When logging was set on DEBUG level on package org.jboss.errai then following message can be observer in server.log https://gist.github.com/agiertli/dff25e7fb09bb313e5eb It seems like jbpm-console is trying to fetch process audit data - they are not there because of AuditMode == NONE --> NPE 2nd observation: AuditTaskImpl and BamTaskSummary tables still includes audit data despite the AuditMode == NONE - this is unexpected. *Log tables are empty - expected. 3rd observation: The NPE was visible only on debug level - please don't swallow the exceptions like this. It's very hard to debug messages like : ""Unexpected error encountered : null" " - it would be better to provide stacktrace in this case.
