Is it possible to edit relationship using ListboxField? According to the documentation it is (AFAIU saveInto() tries to edit relationship), but it doesn't work for me.
Every time I try to create a new record, every item (every Category) is selected in ListboxField.
Saving does not work too - it does not do anything (but there are no errors too).

So the code is:


class Event extends Page {

	static $default_parent = 'EventList';

	static $can_be_root = false;

	public static $db = array(...);

	public static $many_many = array(
		"Categories" => "Category",

	public function getCMSFields() {

		$categoryList = DataObject::get_one("CategoryList");
		$categories = Category::get()->where("ParentID = '".$categoryList->ID."'")->map()->toArray();
			ListboxField::create('Categories', 'Categories')
		, 'Content');


		return $fields;

class Category extends Page {

	static $default_parent = 'CategoryList';

	static $can_be_root = false;

	public static $db = array(

	public static $belongs_many_many = array(
		"Events" => "Event",
