TYPO3.Flow

if you have valueObjects and want to show them in an action controller with
showAction($myValueObject) and get param comes in with &myObject[__identity]=123123-123123-231231
the converting fails because __identity will allways be unset and no other property left after this.
i solved this by simply adding 3 lines in the convertFrom method:

// if there is just only the identity we convert the source to string
if (is_array($source) && count($source) === 1 && array_key_exists('__identity', $source)) {
$source = $source['__identity'];
}

do you agree with it?
