My ckiDate() routine may tell me if a character string represents a discernible date within a given range, but it won't tell me if that date is already booked, so additional edits may require code like:

if booked(order.orderdate);
  sendmsg('orderdate':'Sorry, that date is booked':*on);
  return;
endif;

Would it be that simple in EGL?  I mean that as a sincere question - not knowing what it takes to tie into JSF error handling.
