+
+Reaction::UI::Controller::Role::Action::Delete - Delete action
+
+=head1 DESCRIPTION

+      'Reaction::UI::Controller::Role::Action::Object',
+      'Reaction::UI::Controller::Role::Action::Delete'
+    );
+
+    __PACKAGE__->config( action => {
+      object => { Chained => 'base' },
+      delete => { Chained => 'object' },
+    } );
+
+    sub base :Chained('/base') :CaptureArgs(0) {
+      ...

+
+=back
+
+=head1 ACTIONS
+
+=head2 delete
+
+Chain endpoint with no args, sets up the viewport with the appropriate action.
+If the methods C<on_delete_apply_callback> and C<on_delete_close_callback> are
+present in the consuming class, they will be used as callbacks in the viewport.

+=head2 _build_action_viewport_map
+
+Extends to set the C<delete> key in the map to L<Reaction::UI::ViewPort::Action>
