[TYPO3-mvc] Creating a dynamic back-button for error page

[Claus Due]

Hi,

Welcome to PHP, TYPO3, Extbase and Fluid - impressive, that's one big mouthful ;)

The trick is to use forward, never redirect. If you do so, $this->request->getOriginalRequest() contains the previous request, on which you can call the ->getActionName() and ->getArguments() methods. I think this is what you are looking for - but the hinge is as mentioned that your error display action and return/original action must be placed in the same controller.

Cheers,
Claus

And I can't use the (as it seems to me) dirty way of simply doing a javascript history.back because some actions need to realy reload when going back to them, so I need everything that was in the get-parameters for this action (ActionA above). Is there a referer stored somewhere that I could use?
