Yes, it was clear, but anyway my fault, I don't realized that there is a
factory behind, I just debug into object manager, however nice to know.
I will going to remember this and use it where possible.

Same as my company.contact.0.forename method. Work, but if any error
occur the values of contact fields wont be recovered :\
I believe I will never get the uid until persist the object, right ?
<f:for each="{entry.company.contact}" as="contact">
In this case, contact is the person object an the uid of the person
object only set by persist it. Do the storage have an uid ? I guess no,
so I need the counter / position where is my dummy person in, correct ?

Yes I know. I designed the company object with a possibility to have
more than one contact, but at current time just one contact should be
created.

Another approach :
if (!$entry->getCompany()->getContact()->count()) {
  $contact =
$this->objectManager->getObject('Tx_Myext_Domain_Model_Person');
  $entry->getCompany()->addContact($contact);
}
$this->view->assign('contact', $contact);

Work now with {contact} in the view and send it back with form arguments
{conatct : contact}
and catch contact in the action method and write it back to $entry.
Not tested, just a brainstorm, but may this a solution ?

Greetings Claus
