CakePHP 3 - patchEntity to one model from another

Hi,

I've got a form which updates several tables. The form is for a model (Proposals) that has hasMany relationships to the other tables. The data comes back from the form as the following array:

Array  (      [proposals] => Array          (              [id] => 1              [marketing_source_id] => 16          )        [financials] => Array          (              [asset_price] => 15000              [deposit] => 15              [product] => 11          )        [applicants] => Array          (              [customer_type_id] => 8          )        [assets] => Array          (              [asset_type_id] => 1          )    )
  

I have the following lines of code, to do the patchEntity before the save:

$proposal = $this->Proposals->patchEntity($proposal, $this->request->data['proposals']);

$financial = $this->Financials->patchEntity($financial, $this->request->data['financials']);

The $proposal one works fine, as I'm in the Proposal model. The $financial one gives the errors:

Warning (4096): Argument 1 passed to Cake\ORM\Marshaller::one() must be of the type array, string given, called in /var/www/html/dmv3/vendor/cakephp/cakephp/src/ORM/Marshaller.php on line 149 and defined [CORE/src/ORM/Marshaller.php, line 96]

Warning (2): Invalid argument supplied for foreach() [CORE/src/ORM/Marshaller.php, line 110]

What am I doing wrong? $financial is an entity; if I pass it as an array, it tells me it must be of type entity.

thanks!
