Question on setAddUnknownValues(true) ComboBoxItem

Hi Isomorphic,

is there an easy way in 5.0p to see if the new value of a addUnknownValues:true ComboBoxItem is actually new or selected from the dropdown?
I have a usecase where I want to warn the user that certain functions are not expected to work when he or she enters an unknown value.

Of course I can use addEditorExitHandler and query the Datasource for the entered value, but if the information is already available, I' like to it.

Best regards
Blama
