No. Both must be of the same type. There are several reasons for this: - There is no provision in the EL spec for enum to enum type conversion via a string value - If both A & B are enums, should both values be coerced to enum A or enum B? One may work whilst the other fails. If the spec permitted this then the behaviour in this case would need to be defined. It isn't. - Section 1.17 is clear the String values must be used to trigger enum type conversion > Like the original creator of this post, I have a series of enums of > different types that implement a common interface.
