Bug (?) by using ResponseTrait within a filter

ResponseTrait is not intended to use with filters.
It is for controllers.

Ok, thank you.
I want to check globally in my controller if access is allowed or not. Thats why i tried at first to use the Response Trait in the constructor of my controller but this is not working.

Is it right, that some things, if used in the constructor, not work as expected? The Response Trait is one thing and the setHeader method does not set the header if i use it in the constructor.
