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

The first couple of days were rather frustrating but as far as PHP itself is concerned I can rely on some really experienced co-workers. Typo3 + extbase are a different beast though but I worked myself through it.

That did indeed sound like a fast and easy solution but I couldn't find /use the method getOriginalRequest -> call to undefined method :-(  I'll take a look again but because I'm running out of time (and had to fix some other bugs as well) I came up with another "solution": 

When I run into an error I'm doing a forward, but not to my errorAction but back to the action I was coming from (and to which I wanted to link back from the errorpage). The error message is displayed above and everything else is as it's supposed to be. It works (so far, probably needs more testing), so let's hope the client likes this approach as well.
