TYPO3.Flow

Given following setup:

Domain/Model/SomeObject.php
 1/**
 2 * @FLOW3\Entity
 3 */
 4class SomeObject {
 5
 6    /**
 7     * @var \Doctrine\Common\Collections\ArrayCollection<\TYPO3\FLOW3\Resource\Resource>
 8     * @ORM\ManyToMany
 9     */
10    protected $resources;
11
12    // ...
13
14}

Template.html
1<f:form method="post" action="create" object="{newObject}" objectName="newObject" enctype="multipart/form-data">
2    <f:form.upload property="resources.0" />
3    <f:form.upload property="resources.1" />
4    <f:form.submit value="Create"/>
5</f:form>

If you submit the form, following exception is thrown:

#1337934455: Could not add object of type "MyPackage\Domain\Model\SomeObject" (in PersistenceManager:264)
Warning: spl_object_hash() expects parameter 1 to be object, null given in Packages/Framework/Doctrine.ORM/Classes/UnitOfWork.php line 1509

A similar problem occurs when adding an intermediate object like "File" as OneToMany relation which contains a relation to one resource:

Domain/Model/SomeObject.php
 1/**
 2 * @FLOW3\Entity
 3 */
 4class SomeObject {
 5
 6    /**
 7     * @var \Doctrine\Common\Collections\ArrayCollection<\TYPO3\FLOW3\Resource\Resource>
 8     * @ORM\OneToMany(mappedBy="someObject",cascade={"all"})
 9     */
10    protected $files;
11
12    // ...
13
14}

Template.html
1<f:form method="post" action="create" object="{newObject}" objectName="newObject" enctype="multipart/form-data">
2    <f:form.upload property="files.0.originalResource" />
3    <f:form.upload property="files.1.originalResource" />
4    <f:form.submit value="Create"/>
5</f:form>

In that case the exception is thrown while property mapping already:

#1297759968: Exception while property mapping for target type "MyPackage\Domain\Model\SomeObject", at property path "files.0": Catchable Fatal Error: Argument 1 passed to MyPackage\Domain\Model\File::setOriginalResource() must be an instance of TYPO3\FLOW3\Resource\Resource, null given, called in Packages/Framework/TYPO3.FLOW3/Classes/Reflection\ObjectAccess.php on line 182

So, I'm not sure if that's a problem of the property mapper or the persistence actually. But this was not present before and is a blocker IMO
