XF 2.2 XFCP_Creator not found

[shqawe]

I am trying to add new field to my addon when create thread but when i try to extend Thread\Creator like below:

class Creator extends XFCP_Creator

I got this error

XFCP_Creator not found

and i already add Base class name XF\Service\Thread\Creator and Extension class name shqawe\Demo\XF\Service\Thread\Creator in ACP

So where is the problem in my code?

Posting the full code of the class (instead of just one line that seems to be fine) might be helpful.

Most likely your namespace is not correct.
