Error in Upload required?
I created 2 simple upload forms. Only the uploadfield and a button.
So, when I uncheck the required field the upload, works well (with UE4).
But, if I check the REQUIRED field, the upload doesnt work. I select the same image, click upload, and the error message shows up.
I only use server validation. (means I checked it in the FORM-EDIT/DESIGN area)
