Thought about this some more. Data integrity is lost if changes are made to various attributes under a BO so having this rule work as it does makes sense after-all. I still think having options related to this like not showing it if none of the attributes displayed in the form are changed or having a flag to turn these warnings off for some attributes or BO´s would be useful.
Another related thing is, when we get this message, how about having a refresh button directly on the error modal so we can refresh it right away?
