In Mx 8 the way that an association dragged to a page from the connector pane has changed.
Before the association was added as a reference selector and currently it is being added as a input field.
I find that in most cases this is not the desired option, please revert this to the previous behavior.
I added this before as well, I'll upvote this one too!
I was just about to post the same, you’ve got my vote
