[TYPO3-mvc] How do you get the "next" record when on a detail view?

[Stephen Bungert]

Ok. Thanks.

Your previous function works, but on the last item it shows the first item 
(not sure if you know about this already.

In order to show the previous item when viewing the last item I had to add 
the following to the previous functions query:

->setOrderings(array('uid' => 
Tx_Extbase_Persistence_QueryInterface::ORDER_DESCENDING))

to the function.
