PM89503: EIBAID BECOMES 00 WITH LIGHT PEN, WHEN INPUT DATA LENGTH EXCEEDS 256 BYTES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• In BR/WB env, EIBAID becomes 00, if:
  *
  1. The input screen specifically has Light Pen coded along with
  other AIDs,
  2. The map is RECEIVE'ed via any AID, ie, PFx, ENTER, LIGHT PEN,
  3. Input data length exceeds 256 bytes,
  .
  The reason for it failing in this case is because one of the
  form values within the failing request is quite long and
  due to this length it causes the name/value pair processing
  logic for lightpen requests to terminate early.
  .
  This early termination leaves the AID set at its initial value
  of x00 which is returned and causes EIBAID to be changed as 00.
  .

  * PROBLEM DESCRIPTION: Web Bridge request processing           *
  *                      incorrectly sets EIBAID in lightpen     *

  * RECOMMENDATION:                                              *
  ****************************************************************
  A Web request is sent to the Web Bridge that contains a form
  value that is greater than 256 bytes.  The Web request is
  determind to require lightpen processing and so enters special
  processing.
  
  As the forms data is processed, the logic incorrectly processes
  the field of >256 bytes and this causes the forms processing to
  terminate early causing the EIBAID to get set to an
  uninitialised value of x00 instead of the correct value within
  the forms data.
  

Problem conclusion

• Updated DFHWBTCC to process forms data correctly when the value
  is greater than 256 bytes.
