PK99275: YOU CANNOT ATTACH A CALLBACK TO A FIELD DBE BECAUSE THIS FUNCTION IS NOT CALLED IN THE FUNCTION ENTER

APAR status

• Closed as program error.

Error description

• TLOG#54282
  
  You cannot attach a callback to a field DBE because this
  function is not
  not called if the user type ENTER when the field has the focus,
  which is
  the expected behaviour as described in the help and the
  behaviour with
  previous versions.
  
  
  Here is a piece of code to reproduce the defect :
  When pressing the key ENTER into the field, the message 'yo'
  should be
  displayed. It isn't.
  
  DB db = create('zzz')
  DBE dbez = field (db, 'zzz', '', 10, false)
  void onClose (DB db)
  {
    hide db
  }
  close (db, false, onClose)
  void zzz (DBE dbe)
  {
    ack 'yo'
  }
  set (dbez, zzz)
  show db
  
  
  
  And here is the extract of the DXL help file :
  
  set (select)
  Declaration
  void set(DBE element, void select(DBE))
  
  Operation
  
  Attaches a callback to any dialog box element other than a list
  view. The
  callback must be of the form:
  
  void select(DBE option){
  }
  
  
  which fires when option changes.
  
  The exact semantics vary depending on the type of element, but
  in
  principle it means a single click. For field elements, the
  callback only
  fires when the user clicks Return or Enter with the cursor in
  the field.
  
  If this function is used with a list view, a DXL run-time error
  occurs.
