The objectManager don't contain any object. So I just try this.

if (!$entry->getCompany()->getContact()->count()) {
 	$contact = t3lib_div::makeInstance('Tx_Myext_Domain_Model_Person');
  $entry->getCompany()->addContact($contact);
}

Looks from debugging view that company now contain a person object.

But in the view company.contact is empty, no iteration

and no contact.uid available oO
Is my way of creating dummy person object wrong ? But what else I can do
if $this->objectManager->getObject won't work ?

There is another strange thing. If I instance [1] the entry object, the
company object is missing also (watching from debug). I have to instance
the company object explicit in the entry constructor
$this->setCompany(new Tx_Myext_Domain_Model_Company());
No lazy loading annotations given.

What can be the different to my form ?

public function newAction(Tx_Myext_Domain_Model_Offer $entry = NULL) {
  if($entry == NULL){
    $entry = t3lib_div::makeInstance('Tx_Myext_Domain_Model_Entry');
  }
  $this->view->assign('entry', $entry);
}
