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

[Claus Due]

Hi again,

Forgot to mention that you may need to have {allCards} be an array of uids of records, and then use this:

<f:link action="show" arguments="{card: '{fed:next(haystack: allCards, needle: card.uid)}'">Next card</f:link>

Since I am not sure wether the string treatment of '{fed:next}', which is necessary to trigger the viewhelper call instead of a parse error, will return a proper value to use as a URL argument for your controller.

You would try the first example first, and if that doesn't work move on to the above approach.
