Passing object references

[Drachenkaetzchen]

Hi,

I have setup the hydra demo application from https://github.com/lanthaler/sfHydraDemoApp. I have updated Doctrine to 2.4.7 as there's an issue with PHP 5.6.

I have successfully created a new user in the database. Now I'm trying to create a new issue in the demo app, and I'm trying to figure out what to pass as the parameter "raisedBy". I tried the numeric ID of the user and "/~felicitus/hydrademo/web/app_dev.php/api/users/1" - both result in the following error:

{
  "@context": "/~felicitus/hydrademo/web/app_dev.php/api/contexts/Error",
  "@type": "Error",
  "hydra:title": "An error occurred",
  "hydra:description": "Warning: spl_object_hash() expects parameter 1 to be object, string given",
  "trace": [
    {
      "function": "handleError",
      "class": "Symfony\\Component\\Debug\\ErrorHandler",
      "type": "->",
      "args": [
        2,
        "spl_object_hash() expects parameter 1 to be object, string given",
        "/home/felicitus/public_html/hydrademo/vendor/doctrine/orm/lib/Doctrine/ORM/UnitOfWork.php",
        1389,
        {
          "entity": "/~felicitus/hydrademo/web/app_dev.php/api/users/1",
          "assume": 2
        }

Any clue what's going on?
