[Flow] Converting Objects by additional identity does not work?

[Carsten Bleicker]

but why this exists in persistent object converter?
\TYPO3\Flow\Property\TypeConverter\PersistentObjectConverter::findObjectByIdentityProperties
this exactly seems to do what i want. but only if an array with identities comes in.
seems not to work if string with foreign id comes in.
