APAR status

• Closed as program error.

Error description

• SVCDataExposure doesn't override Progress.equals(), and also
  doesn't pass in unique fields to it's
  super class (which does implement equals).  As a result, when
  the data exposure changes, the old
  SVCDataExposure  object and the new SVCDataExposure  object
  compare as equivalent.  Thus, the GUI
  doesn't get the event that the DataExposure changed, and keeps
  showing the old value.
  This evident in the logs. Particularly, dataExpTime does not
  change in gui xml trace. In the example
  below, notice: dataExpTime="00:19:31":
  """"""""""""""""""""""""""""""
