Steps to reproduce:

1. Go to the backend and create a new content of type "Poll" and create a test question with some test options;
2. Publish;
3. Go to the frontend and access the poll page. Don't click on "Vote". Instead, click on the "Result" link. An "Object is unavailable" error will be displayed.

Notes:

• if you click first on "Vote" and then go back and click on "Result", the error will not be displayed;
• after you clicked on "Result" and got the error, if you go back, click on "Vote", then click on "Back to poll" and click on "Result" again, the error will also not be displayed.
