I want to make a LotteryPage. Now I have participiant-objects and a gridfield to display them. For the lottery I want to create a custom action (with a twist). Before finding the winners, the CMS User has to put in the number of wanted winners.
I got this working with a Form. analogue to the GridField_URLHandler - Tests. Anyhow, after completing the task, I want to redirect back to the gridfield's page.
Is this possible? I couldn't figure out the Backlink() function from the Detailform somehow ...
