[TYPO3-mvc] Best practice for ajax json_encode on repository of model

When encoding your extbase objects, the native PHP function
json_encode() will not consider protected attributes - which you
probably are using. You might implement a simple "serialize" method
in your objects, producing a suitable (associative, nested) array. Or
have a look at the JsonSerializable interface*.

Cheers, 
Ludwig
