+ As explained in the new_from example, it is possible to set transdate to a new value.
+ From a user / programm point of view transdate is more than holy and there should be
+ some validity checker available for controller code. At least the same logic like in
+ Form.pm from ar.pl should be available:
+ # see old stuff ar.pl post
+ #$form->error($locale->text('Cannot post transaction above the maximum future booking date!'))
+ # if ($form->date_max_future($transdate, \%myconfig));
+ #$form->error($locale->text('Cannot post transaction for a closed period!')) if ($form->date_closed($form->{"transdate"}, \%myconfig));
