Validation rules are ignored with patchEntity

Hi, why are my validation rules getting ignored? i do:

 $parkalbumimage = $this->Parks->Parkalbums->Parkalbumsimages->newEmptyEntity();


parkalbumimage = $this->Parks->Parksalbums->Parkalbumsimages->patchEntity($parkalbumimage, $requestData, ['validate' => 'addb']);

if i change the name of the validation set to one that doesnt exist there will come an error… but with one that exists it will just ignore everything inside…

any idea?

the problem is solved… propably only a cache issue
