[FLOW3-general] Extended Person, initializeUpdate Problem

[Martin]

Hi Folks,

at the moment I am struggeling with an extended PersonModel
It's creation is fine but the update isn't working so far.

In "class Student extend [..]\Person" I got the field matrikel
It gets set by creation. Everything is fine by now. But when it gets to 
an update I get this error:
"Exception while property mapping at property path "party": Property 
"matrikel" was not found in target object of type 
"\TYPO3\Party\Domain\Model\Person"

My initializeUpdateAction looks like this:

/**
* @return void
*/
public function initializeUpdateAction() {
	 
//$this->arguments['account']->getPropertyMappingConfiguration()->setTargetTypeForSubProperty('party','\Abgabe\Domain\Model\Student'); 
$this->arguments['account']->getPropertyMappingConfiguration()->setTargetTypeForSubProperty('party','\TYPO3\Party\Domain\Model\Person');
$this->arguments['account']->getPropertyMappingConfiguration()->allowModificationForSubProperty('party');
$this->arguments['account']->getPropertyMappingConfiguration()->allowModificationForSubProperty('party.name');
$this->arguments['account']->getPropertyMappingConfiguration()->allowModificationForSubProperty('student');
}

In my view I get the right data with calling party.matrikel even it's 
stored in student.

I was looking in the conferencePackage they have an extra class related 
to nothing for storing extra Information. Is that the way?
