[TYPO3-mvc] 6.2: How to debug recursive validation

[g4-lisz at tonarchiv.ch]

Hi all

I had to reanimate this thread...

I had an issue with the validation validation because of some object
getter methods, which use findBy() through repositories.

E.g.

        /**
         * Returns the messung
         *
         * @return
Tx_Extbase_Persistence_ObjectStorage<Tx_Hplusinfo_Domain_Model_Messung>
         */
        public function getMessung() {
                $repository = new
Tx_Hplusinfo_Domain_Repository_MessungRepository();
                return $repository->findByKlinik($this);
        }

This worked in 4.6.

But now, findByXxx() returns the wrong type: "The given subject was not
a collection."

How can I solve this? I know that it's not nice to have this kind of
getter. But at the moment there is no other way to have the children
sorted in fluid, if only the parent object is passed to the template.

Like: <f:for each="{klinik.messung}" as="messung"> ... </f:for>
