How does your update action look like? Something like this?

function updateAction(Tx_ExtKey_Domain_Model_Company $company) {
	$this->companyRepository->update($company);
}

Or do you update you $company object by hand via something like this:

function updateAction(Tx_ExtKey_Domain_Model_Contact $contact, 
Tx_ExtKey_Domain_Model_Company $company) {
	$company->setContact($contact);
	$this->companyRepository->update($company);
}

The later has to work in any way - the previous might have an issue with 
the argument mapping, memorizing the clean state at a wrong stage.

Please tell me which way you do it and I'll have a look at the 
responsible codes.
