-         * (on new event creations). Whereas the TKT_is_default_selector is for the user to indicate they want
-         * this ticket to be saved as a default.
-         * The tricky part is, on an initial display on create or edit (or after manually updating),
-         * the TKT_is_default_selector will always be unselected and the TKT_is_default will only be true
-         * if this is a create.  However, after an autosave, users will want some sort of indicator that

-         * in other words we don't want to remove the check on TKT_is_default_selector. So here's what I'm thinking.
-         * On Autosave:
-         * 1. If TKT_is_default is true: we create a new TKT, send back the new id and add id to related elements,
-         * then set the TKT_is_default to false.
-         * 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.
