JR48896: TIMEOUT HANDLING ISSUE IN PROCESS PORTAL WHEN REST TIMEOUT OCCURS DURING LAUNCHING OF A TASK (LOADING OF A COACH)

APAR status

• Closed as program error.

Error description

• In Process Portal, when creating or opening a task that
  initiates loading of a coach, if a REST request timeout occurs,
  the text "Loading..." is displayed on a blank screen (until the
  user refreshes the browser or navigates elsewhere in Process
  Portal).  (For BPM Version 8.0.1.2 and Version 8.5.0.1, the
  timeout is 30 seconds; for earlier versions, the timeout is 20
  seconds.)  When a timeout occurs, a dialog displaying the
  message "The service is not currently available." should be
  displayed, after which the task completion user interface should
  close when the user clicks the OK button on the dialog.
  
  Note that in the case of task creation, the task is correctly
  created and the user can work with the task (provided another
  REST request timeout does not occur during coach loading).

  ****************************************************************
  When a user selects a task on the Work tab to work on the
  task, several REST calls occur before the coach is opened,
  including calls which determine the actions to which the user
  is entitled.  The error handler for these REST calls was
  accessing the status code of the response without checking to
  determine whether a timeout occurred.  This is important
  because the timeout is triggered on the client side and
  therefore no proper response with status code is available.
  

Problem conclusion

• A fix is available that ensures that the error handler for
  the REST calls does not access the status code of the
  response before checking that a timeout occurred; if a timeout
  is detected, the fix displays an informative error message
  instead of the text "Loading..." (indefinitely).
