Downloading IBM Business Process Manager V8.5.7 Cumulative Fix 2016.09

APAR status

• Closed as program error.

Error description

• When you run a process instance that has a conditional activity
  and that conditional activity has at least one boundary event,
  the instance stays in the active state although all tasks and
  required ad hoc activities are completed and no intermediate
  events are waiting.
  

Local fix

• When you require an activity to run based on a condition and you
  also need boundary events on that activity, do not define the
  activity to be conditional. Instead, use an exclusive gateway
  before the activity to either run the activity or prevent the
  activity from running.
  

Problem summary

• When you define an activity to be conditional, its condition is
  evaluated when a token reaches it to check if the activity
  should run or to be skipped. This condition was incorrectly
  evaluated again when the activity was completed. If the
  condition was false during the second evaluation, processing the
  activity stopped and the process continued. At that time,
  tokens for boundary events on this activity were not removed
  and, therefore, caused the instance to stay in the active state.

Problem conclusion

• A fix will be included in IBM BPM V8.5.7 cumulative fix 2016.09
  that ensures the tokens of boundary events are correctly cleaned
  up and that allows you to change the behavior so the business
  process definition (BPD) engine BPM evaluates the condition only
  when the activity is created and not when it is completed.
  
  To determine whether the cumulative fix is available and
  download it if it is, complete the following steps on Fix
  Central:
  
  1. Select IBM Business Process Manager with your edition from
  the product selector, the installed version to the fix pack
  level, and your platform, and then click Continue.
  2. Select Text, enter ?cumulative fix?, and click Continue.
  
  To change the behavior of the BPD to check the activity
  condition only when the activity is created, edit your IBM
  Process Center and IBM Process Server 100Custom.xml files to
  match the following entry:
  
  <server>
    <bpd-engine merge="mergeChildren">
       <evaluate-condition-only-on-activity-creation
        merge="replace">
         true
       </evaluate-condition-only-on-activity-creation>
    </bpd-engine>
  </server>
