JR40254: HUMAN TASK WIDGET RECONFIGURATION BY ADDING FUZZY OR STRING FILTERS CAUSES ERROR

IBM Business Monitor V7.5 Refresh Pack 1 (7.5.1)

APAR status

• Closed as fixed if next.

Error description

• In the Human Task widget, the first time you set a "fuzzy"
  filter or string filter and save it, the filter works correctly;
  however, editing the filter again and saving it results in
  failure of the filter, with no instances displayed in the
  widget. Error messages similar to those shown below are written
  to SystemOut.log in the server or cluster where REST services is
  deployed.  This condition persists until you delete the filter
  (and save the change), after which you can again set a new
  "fuzzy" or string filter, once.
  
  Error messages in SystemOut.log:
