Downloading IBM Business Process Manager V8.5.7 Cumulative Fix 2017.03

APAR status

• Closed as program error.

Error description

• When user tasks of a process are implemented by a heritage human
  service that has multiple coach steps, a user might start the
  human service for the same task more than once in multiple
  browser windows or browser tabs.
  Using IBM Process Portal, for example, a user might open the
  task in a new window if the corresponding option is set.
  For another example, the user might click the link of an email
  notification from IBM Business Process Manager (BPM) more than
  once.
  In either of these examples, the human service is navigated
  concurrently in the different browser windows or tabs, leading
  to exceptions like this one in the system log:

  The user task implementation fails and error handling in the
  process is triggered or, if no error handling logic is part of
  the process model, the process instance is in the failed state.

Local fix

Problem summary

• When a user submits the data of a coach by triggering a boundary
  event, the runtime environment applies the data changes to the
  task instance and tries to continue navigating to the heritage
  human service. If multiple browser tabs are used, the data and
  boundary event that the user sends might not match the current
  state on the server.
  

Problem conclusion

• A fix will be included in IBM BPM V8.5.7 cumulative fix 2017.03
  that ensures that requests sent from the browser to the server
  are accepted only if the service state in the browser matches
  the state on the server.
