"Just create a new web page with your Edit Form and follow the article."
Unfortunetly this was the problem i was facing. But i think i got it now. Thanks for replying lashyn and Oliver.
I created a webpage, connected the entity form and added the webpage to the "on success setting" at the create form.
It works, but not perfect. Maybe you have an idea to fix it without javascript?
When i create the new record i get redirected to the "edit-Form" but on a whole new page. But i want it just to fade to the edit Form like in your blog post oliver. Is that possible?
Cheers and have a good day!
