-         * 2. If TKT_is_default_selector is true: we create/edit existing ticket (following conditions above as well).
-         *  We do NOT create a new default ticket.  The checkbox stays selected after autosave.
-         * 3. only on MANUAL update do we check for the selection and if selected create the new default ticket.
