100 This subclass of L<Reaction::UI::ViewPort::Object::Mutable> is used for
101 rendering a complete form supporting Apply, Close and OK.
109 Inherited from L<Reaction::UI::ViewPort::Object::Mutable>. Must be a
110 L<Reaction::InterfaceModel::Action>.
112 Also handles C<error_message> and C<has_error_message> methods.
120 Returns true if a field has been edited.
126 Returns true if no field C<needs_sync> and the L</model> C<can_apply>.
130 Delegates to C<do_apply> on the L</model>, which is a
131 L<Reaction::InterfaceModel::Action>.
133 =head2 sync_action_from_fields
135 Firstly calls C<sync_to_action> on every L<Reaction::UI::ViewPort::Field::Mutable>
136 in L<fields|Reaction::UI::ViewPort::Object/fields>. Then it calls C<sync_all> on
137 the L<Reaction::InterfaceModel::Action> in L</model>. Next it will call
138 C<sync_from_action> on every field to repopulate them from the L</model>.
