Local fix

Problem summary

• IBM BPM V8.5.0 introduced an objectId property in the metadata
  of a business object to identify the business object.
  
  This property is automatically filled when a business object is
  created. When navigation in a heritage human service from a
  coach step returns to the same coach step?either by using wires
  or a Stay On Page event?the coach is not completely refreshed;
  only the changed data applies.
  
  IBM BPM V8.5.6 enhanced the logic to use the objectId property
  to determine which data changed. This enhanced logic is used
  only for process applications that use the system toolkit in
  V8.5.6 or a later releases. However, this logic fails because
  the objectId is not set when you have an IBM BPM deployment
  environment earlier than V8.5.0 with active instances and you
  perform the following steps:
  
  1. Upgrade the IBM BPM deployment environment to V8.5.6 or
    V8.5.7.
  
  2. Install a new snapshot of your process application that uses
    the new system toolkit version.
  
  3. Migrate active instances to that new snapshot.
  
  4. Run a heritage human service.
  

Problem conclusion

• A fix that automatically initialized the objectId property when
  it is not yet set will be included in an upcoming IBM Business
  Process Manager (BPM) V8.5 cumulative maintenance vehicle.
  
  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.
