On my page layouts with required look up fields I have an odd issue. When I click publish, even though the fields are filled in, I get this message "You must fill out all required properties before completing this action." If I save first, I do not get this message when I publish. I noticed that the publish isn't triggering the save operation on pages with look up fields.
I've read a few articles and it sounds like a known bug? Is there a known fix for it?
