APAR status

• Closed as program error.

Error description

• When the auto field advance feature is turned on in HATS, and
  users type quickly, characters can be lost in the time it takes
  for the cursor to move from one field to the next.  If a user is
  typing quickly they may not notice this happening and this could
  cause the wrong data to be entered or omitted on the screen.
  

Local fix

• Currently the only options would be to turn off auto advance or
  to type slower.

  ****************************************************************
  Currently the updateCursorPosition function, which is
  triggered by the automatic field advance in HATS, is being
  called in the keyuphandler method in KBS.js.  In certain
  cases, where users type quickly, this event is fired too late
  and is not able to be processed fast enough before the next
  keystroke comes in.  As a result, the next keystroke does not
  show up in the input field while the focus is being shifted
  and that character is lost.
  

Problem conclusion

• The keydownhandler method in KBS.js was modified to call the
  updateCursorPosition function to allow the cursor to be
  shifted to the next available input field sooner.  The
  keyuphandler method will continue to call the
  updateCursorPosition function as well so that the focus will
  be shifted to the next field immediately when the current
  input field is full.
