Flows for APEX - Changelog

v23.1

  • Allows process variable substitutions to be used in all of the parameters of an APEX Page task.
  • Adds 'is Startable' information to Processes, along with users and groups that can start a process.
  • Allows BPMN diagrams to contain Groups and attached Annotations.

  • Enhances Flows for APEX Application dashboard to display process and step performance, errors, and waiting time statistics.
  • Adds auditing / logging of changes made to process diagrams, to complete the existing logging capabilities
  • Adds the ability to create a summary document, as a JSON document, describing all actions taken to run a process instance.
  • Adds an Automation creating archive summaries for all recently completed process instances into an archive table or OCI Object Storage.
  • Adds an automation for automated purging of old logging data and statistics summaries.
  • Allows an administrator to easily change the timer polling frequency, or temporarily enable / disable timers on non-production systems.
  • Experimental Feature - Adds MessageFlow between sendTasks, receiveTasks, Intermediate Message Catch and Throw events. Phase 1 of more...
  • Adds support for additional languages Italian, Simplified Chinese, Traditional Chinese, Korean.
  • Required APEX version increased to APEX v20.2

v22.2

  • Adds BPMN Call Activities, allowing a process diagram to call another process diagram, passing and returning in/out variables.
  • Adds scoping to process variables at diagram level to support call activities.
  • Support for timer, escalation, and error boundary events on call activities.
  • Adds support for Oracle APEX Approval Tasks when running with APEX v22.1 and above. Approvals are called as a type of bpmn:userTask.
  • Adds an Approval Result Return process plug-in for declarative configuration of Approval Tasks.

  • Makes processVariable naming case-independant, so that myVar and MYVAR are the same variable.
  • Creates an APEX session for non-APEX originated end points, ensuring that variable expressions, debugging, etc. work correctly from non-APEX API calls, after timers, from test engines, etc.
  • Changes Lane processing from parse-time to step-run-time to facilitate call activities with or without lanes in any involved diagram.
  • Internally enhances storage of parsed BPMN object attributes using JSON structures in place of the flow_object_attributes table.
