[TYPO3-mvc] editAction doesn't work

[typo3 at markus-guenther.de]

Hello,

i am a new and bein to program extension with extbase. I am in
industrial training but the most are programming pi base extensions. so
i hope that one of you can tell me why my updateAction dont work.

I want build a extension that offers users the possibility to subscribe
for appointments. A Appointment only have a date an some Timeslots and
the User can subscribe for a Timeslot and enter a name and a date.

But when i want to update a timeslot extbase can not find the object in
the repository. any id is not given so he can not know from wich object
it comes.

Timeslot controller:
	/**
	 * Displays a form to edit an existing timeslot
	 *
	 * @param Tx_XXX_Domain_Model_Timeslot $timeslot The timeslot to
display
	 * @dontvalidate $timeslot
	 */
	public function editAction(Tx_XXX_Domain_Model_Timeslot $timeslot) {
		print_r($timeslot);
		$this->view->assign('timeslot', $timeslot);
	}

	/**
	 * Updates an existing blog
	 *
	 * @param Tx_XXX_Domain_Model_Timeslot $timeslot The timeslot to modify
	 * @return void
	 */
	public function updateAction(Tx_XXX_Domain_Model_Timeslot $timeslot) {
		print_r($timeslot);
		$this->timeslotRepository->update($timeslot);
		$this->flashMessageContainer->add('Your timeslot was updated.');
		$this->redirect('index', 'Appointment');
	}


MODEL for Timeslot:

class Tx_XXX_Domain_Model_Timeslot extends
Tx_Extbase_DomainObject_AbstractValueObject {

	/**
	 * time of a Timeslot
	 * @var string
	 * @validate NotEmpty
	 */
	protected $time;

	/**
	 * name of a attendee at this timeslot
	 * @var string
	 */
	protected $name;

	/**
	 * name of a attendee at this timeslot
	 * @var string
	 */
	protected $phone;

	/**
	 * Setter for time
	 *
	 * @param string $time time of a Timeslot
	 * @return void
	 */
	public function setTime($time) {
		$this->time = $time;
	}

	/**
	 * Getter for time
	 *
	 * @return string time of a Timeslot
	 */
	public function getTime() {
		return $this->time;
	}

	/**
	 * Setter for name
	 *
	 * @param string $name name of a attendee at this timeslot
	 * @return void
	 */
	public function setName($name) {
		$this->name = $name;
	}

	/**
	 * Getter for name
	 *
	 * @return string name of a attendee at this timeslot
	 */
	public function getName() {
		return $this->name;
	}

	/**
	 * Setter for phone
	 *
	 * @param string $phone phone number of a attendee at this timeslot
	 * @return void
	 */
	public function setPhone($phone) {
		$this->phone = $phone;
	}

	/**
	 * Getter for Phone
	 *
	 * @return string phone of a attendee at this timeslot
	 */
	public function getPhone() {
		return $this->phone;
	}
}
?>


REPOSITORY:

class Tx_XXX_Domain_Repository_TimeslotRepository extends
Tx_Extbase_Persistence_Repository {
}
?>


TEMPLATE:


i use in the index.html from the appointment which is the entity.

<f:link.action controller="Timeslot" action="edit" arguments="{timeslot
: timeslot, appointment : appointment}">edit</f:link.action>

and the edit.html  from timeslot contains this

<div class="XXX">

	<f:flashMessages id="XXX-flashMessages"/>

	<div class="XXX-appointment-edit">
		<h2 class="XXX-appointment-header"><f:translate
key='tx_XXX_domain_model_timeslot.edit-head' /> - {timeslot.time}</h2>
		<f:form method="post" action="update" name="timeslot"
object="{timeslot}">
			<div>
				<label for="time"><f:translate
key='tx_XXX_domain_model_timeslot.edit-time' /></label>
				<f:form.textbox property="time" />
			</div>
			<div>
				<label for="name"><f:translate
key='tx_XXX_domain_model_timeslot.edit-name' /></label>
				<f:form.textbox property="name" />
			</div>
			<div>
				<label for="phone"><f:translate
key='tx_XXX_domain_model_timeslot.edit-phone' /></label>
				<f:form.textbox property="phone" />
			</div>
			<button class="std-button" type="submit" name="submit" value="edit">
				<em>
					<span><f:translate key='tx_XXX_domain_model_timeslot.edit-save'
/></span>
				</em>
			</button>
			<div class="clear"></div>
		</f:form>
	</div>
</div>
