[TYPO3-mvc] Typolink keepPIvars with extbase

[Loek Hilgersom]

Hi,

I'm trying to make an extbase/fluid extension that works on top of 
tt_news (no chance to replace that by the extbase news, as much as I 
would like to do that, not yet), but I'm running into to trouble with 
the redirect after actions. It should redirect to the news singleview 
page but it looses the tt_news get-parameters on the way.

I managed to solve this for the normal successful actions by creating 
the proper link and using redirectToURI instead of redirect, but as soon 
as a form validation error is shown extbase itself redirects to the page 
without the tt_news parameters.

Is there a way to make extbase use something like the 
pi_linkTP_keepPIvars_url() functions? Or what would be the proper way to 
handle this?

Thanks,
Loek
