[TYPO3-mvc] The given subject was not a collection..

[Thomas Hucke]

Hi Philipp,

I also had this error trying my ext in the new version.
I figured out the the issue in my case was an obviously wrong annotation in 
my model.

The request is being validated - just before it gets passed to your 
controller action.
I got some 1:1 relations in my model and for thos relations I made 
annotations like
    @var 
\TYPO3\CMS\Extbase\Persistence\ObjectStorage<\<myVendor>\<myExtkey>\Domain\Model\<myModel>

Unfortunately during pre-procession the createAction TYPO3 builds a 
collection of validators that should be called to check the request.
When <myModel> is being checked there´s a component TypeHandlingUtility that 
tells T3 "Hey - this parameter <myModel> must be a collection because it´s 
of the type Objectstorage." Hence the following CollectionValidator expects 
a collection type var.
TypeHandlingUtility defines the following colltionstypes:
static protected $collectionTypes = array('array', 'ArrayObject', 
'SplObjectStorage', 'TYPO3\\CMS\\Extbase\\Persistence\\ObjectStorage', 
'Tx_Extbase_Persistence_ObjectStorage');

If you got a 1:1 relation change your annotation to
   @var \<myVendor>\<myExtkey>\Domain\Model\<myModel>


Then clear all caches and - just to make sure really ALL cached info is 
removed - also both directories in typo3temp/Cache.
Then open a phpadmin session and truncate all tables starting with cf_*. I 
gained the experience that some source code is being cached by the framework 
so it made no difference only changing the source code.

Good luck
Thomas

I try to validate a new object manually, in the action i get an array passed 
and build a valdationObject like this:
$validatorResolver = 
$this->objectManager->get('TYPO3\\CMS\\Extbase\\Validation\\ValidatorResolver');
/* @var $validatorResolver \TYPO3\CMS\Extbase\Validation\ValidatorResolver 
*/
$modelName = $this->requestService->getModelName($request->getKey());
$validator = $validatorResolver->getBaseValidatorConjunction($modelName);

I need this because i want to use different request objects with different 
validations

now the problem is, that an array like

request : {key:1,identifier:1,package:12}

is validated recursively, but i am passing a allready created entity...

now of course i get validation errors for those properties.

How do i solve this?
