Redirect problem

Hello,

I have problem figuring out how to redirect from non action method. I found solution:

Redirect:back()->send();

this works perfectly, however when I add messages to it:

Redirect:back()->with('success', 'Something finished successfully.')->send();

page is redirected, unfortunately session flash messages are getting lost.

For now I return whole redirect object from protected method to action method, but I would like to fire redirect directly from protected non action method and thus avoid unnecessary object passing.
