TYPO3 Core

Consider the following action:

/**
 * @param \Vendor\Ext\Domain\Model\MyModel $myModel
 * @param \TYPO3\CMS\Extbase\Persistence\ObjectStorage<\Vendor\Ext\Domain\Model\MyModel>    $myModelList
 */
public function objectStorageAction($myModel, $myModelList)

Validation of first argument is executed, also due to recursive validation sub-properties are validated too, including validation of ObjectStorages and elements inside of them.

Validation of second argument is not executed, and so no validation of elements is performed.

This can be fixed with annotation:

@validate $myModelList Collection(elementType=\Vendor\Ext\Domain\Model\MyModel)

But would be much more convenient, if ExtBase could detect it from @param definition.
