That would seem to depend on what get_next_project_number() does, the
contents of which are unknown. get_next_project_number() gets the next
project-number based on some custom logic. What would be the best way to
update all project's project-number having the oldes project get the first
number returned by get_next_project_number() etc.? Thanks. --
