[TYPO3-mvc] yes, nested objects validation is a missing feature at current extbase version (1.3)

[Eric S. Auchterberge]

Thanks you Steffen for such snippet based answer, which provided fast
guidance to use getBaseValidatorConjunction().

Notice that the clause:

   if(!is_object($value) || $value instanceof
Tx_YourExtensionName_Domain_Model_YourModelName) {
                       return FALSE;
               }

must be:

   if(!is_object($value) || !($value instanceof
Tx_YourExtensionName_Domain_Model_YourModelName)) {
                       return FALSE;
               }

Regards,
Eric
