So I have a pretty basic scenario. Two lists (Projects and Clients). In the Projects list I have a mandatory lookup field that aims at the Clients Title column.
Now when I fill out the form for creating a new Projects list item and try to save it the form just reloads and nothing is created. There are no error messages what so ever.
It works when I set the column to not required, but well that's not a solution.
what am I missing?
