I have set up a list with two content types. When I click the New Item button, a dropdown is displayed which contains the two content types. So far so good. However, the forms behind those buttons are incorrect: in both forms, only the columns from the default content type are shown. If I check the urls of the 2 forms, I can see that the correct content type id is in the querystring. But still, the contents of the form are incorrect.
Any ideas?
