Grails filters after action return value

Question

Should I return boolean from the "after" grails filter action? I think it is useless, I need confirmation

Answer 1

In my experience, I also do not need. The filter "after" is started after the logic of the controller and before the visualization of the template. The rendering phase will occur no matter what you return from the after filter.

Answer 2

A return boolean false before closing will prevent all future filters and actions from executing.

As Tri points out, the return value after closing is not affected.
