I keep getting this error Undefined offset: 14 in vendor/bundles/JMS/SerializerBundle/Metadata/PropertyMetadata.php line 110 I have tried removing numerous fields from my model but no luck. Here is what I am trying to serialize.
(
[id:protected] => 4f6b899196acb81b17000006
[name:protected] => Test File
[url:protected] =>
[owner:protected] => BIMFS
[prefix:protected] => None
[dead_date:protected] =>
[created:protected] => 2012-03-22T15:20:33-05:00
)

/**

• @xmlRoot("package")

• @mongodb\Document
  */
  class FileRecord
  {

  /**

  • @mongodb\Id
    /
    protected $id;
    /*
  • @mongodb\String
    /
    protected $name;
    /*
  • @mongodb\String
    /
    protected $url;
    /*
  • @mongodb\String
    /
    protected $owner;
    /*
  • @mongodb\String
    /
    protected $prefix;
    /*
  • @mongodb\Date
  • @type("DateTime")
    /
    protected $dead_date;
    /*
  • @mongodb\Date
  • @type("DateTime")
    */
    protected $created;
    }

Thanks,

If I print out the str var from deserialize I get this
a:14:{i:0;N;i:1;N;i:2;N;i:3;N;i:4;b:0;i:5;b:0;i:6;N;i:7;N;i:8;b:0;i:9;b:0;i:10;N;i:11;N;i:12;b:0;i:13;s:66:"a:2:{i:0;s:35:"BIM\BimfsBundle\Document\FileRecord";i:1;s:2:"id";}";}

This usually means, that you forgot to clear the cache after you updated the vendors.

That seems to be the case. Thanks for the help :)
