      Description

      Doctrine won't persist object if it is empty (all fields are nulls). Not sure if it is bug or expected behavior, but sometimes it causes inconvenience. Test case:

      /** @Document(db="tests", collection="tests") */
      class a
      {
          /** @Id */
          protected $id;
      
          /** @String */
          protected $b;
      }
      
      $a = new a();
      $dm->persist($a);
      $dm->flush(); // $a won't be inserted
      

      There is also related issue: when embedding empty object (all fields are nulls) embedded object is not saved.

      /** @Document(db="tests", collection="tests") */
      class a
      {
          /** @Id */
          protected $id;
      
          /** @String */
          protected $tmp = 'WorkaroundToBeSaved';
      
          /** @EmbedOne(targetDocument="b", cascade="all") */
          protected $b;
      
          function getId()  {return $this->id;}
          function getB()   {return $this->b;}
          function setB($b) {$this->b = $b;}
      }
      
      /** @EmbeddedDocument */
      class b
      {
          /** @String */
          protected $val;
          function setVal($val) {$this->val = $val;}
          function getVal() {return $this->val;}
      }
      
      $a = new a();
      $a->setB(new b());
      
      $dm->persist($a);
      $dm->flush();
      $dm->getUnitOfWork()->clear();
      
      $a = $dm->loadByID('a', $a->getId());
      $c = (null !== $a->getB()); 
      var_dump($c); // returns false, while expecting true
