Hi, I am using SP 2010m and successfully set up cascading dropdowns. It works perfectly in NewForm, and I can see it saves the data in list view. However, when I go to Disp or Edit, 1 out of the 5 “dropdowns” populates a blank value – but there was a value assigned (and available). Again, it does display the right value in the list view.
Another weird thing is that it displays one of my cascading drop downs in the wrong tab (only in disp or edit). When I click on another tab and go back – it moves it to the right tab.
