Dates are usually bound from multiple fields i.e. yearDate_year,
yearDate_month, yearDate_day etc. I think it is probably looking for
these and failing. I don't think the current date binding supports
mapping incoming strings to dates - after all what format should they
come in (bear in mind locale issues etc)
