[TYPO3-english] Re: why are flash messages not displaying on some pages

[Calgacus map Brude]

ok, found the issue just by chance:

If I assign an object to be rendered on my view then flashmessages start to show.  for example :

 $this->flashMessageContainer->add('Valid.');
 $this->view->assign('coupon', $coupon);
 $this->redirect('validate_success');

Now the flash message shows, without the assign line - nothing.
