An error is triggered when accessing an enumerated type value which does not exist. DVT provides an easy way to easily declare the missing value.
Place the editor cursor on the error's line and press Ctrl + 1, select Declare enum type value ... from the list of quick fix proposals and press Enter.
The new value is inserted in the type declaration.
