How to display comment using FOSCommentBundle Symfony

Question

I want to integrate comments in my web page. So that I used the Symfony2.3 Bundle FosCommentBundle. I followed the steps indicated in the Bundle documentation , but in the fourth step nothing happens on the generated page and I get ajax 500 Internal error:

http://127.0.0.1/ecomerce/web/app.php/api/threads/1/comments?permalink=http%253A%252F%252F127.0.0.1%252Fecomerce%252Fweb%252Fapp.php 

I didn't find plenty of tutorials about this bundle. Is there any js file I have to include it on my page to make it works?

Answer 1

I resolved the problem by clearing the cache.
