I have two content types with CCK fields. One type includes a CCK field that is a node reference, the other includes a CCK field that is a user reference. Both field are Select List widgets based on Views. The view results sets are as expected when previewing them; however, I just installed the latest Views dev version (date stamped 1256344316) and when creating content the select lists are empty. I reverted to the previous dev version (date stamped 1255998945) and the select lists are populated fine.
If you need me to provide more info I would be happy to do so - I just don't know where to look.
