Workflow release notes Workflow product enhancements and updates in the Istanbul release. New in the Istanbul release Workflow property to catch errors during pre-processing stage Workflow includes a new property that controls how the system reacts to errors when executing an activity during the pre-processing phase. In previous releases, the system continued processing a workflow when it encountered an error when pre-processing an activity. In Istanbul, the system may stop processing a workflow in this situation. This change may cause some workflows to fail that previously did not.To stop executing a workflow for a pre-processing error, navigate to Workflow > Administration > Properties, then check Use this to catch errors during the pre-processing stage of workflow activities. To continue executing a workflow when a pre-processing error occurs, uncheck this property.
