*
* $compoundForm->submit($arrayOfChildrenViewData)
* // inside:
* $childForm->submit($childViewData);

* $this->dataMapper->mapFormsToData($compoundForm, $compoundInitialViewData)

* When a simple form is submitted the following is happening:
*
* $simpleForm->submit($submittedViewData)
* // inside:
* $this->viewData = $submittedViewData
* // then reverse transform
*
* The model data can be an array or an object, so this second argument is always passed
* by reference.
