Upgrade 2.2 to 2.5 - ezobjectrelationlist_field fails

Hi everybody,

After Upgrading to the new LTS Version 2.5 from 2.2 everything in FE and BE works find except content elements with a relation field (ezobjectrelationlist_field) as attribute. I cannot open, edit or publish content elements with these kind of attributes. This is my error message:

An exception has been thrown during the rendering of a template ("Could not find ‘Content’ with identifier 'array (

‘id’ => 665,
‘languages’ =>
array (
0 => ‘eng-GB’,
),
‘versionNo’ => NULL,
)’") in “EzPlatformAdminUiBundle:fieldtypes/preview:content_fields.html.twig”.

Did something change to the relation fields in the last releases? I doubled checked the upgrade guide but could not find any help.
