[bind] Error: Error during validation: Internal error: instance
signatures not found for class com.sdm.data.enums.ContentType; on value
element at (line 62, col 85, in src/main/resources/binding.xml)
The Enum class is generated following the typesafe enum pattern. It
implements Serializable and an interface called Displayable which only
contains the methods String getDisplayName(); and String
getDisplayName(Locale pLocale);
The enum is serialized and deserialized in JiBX through a custom serializer
/ deserializer referenced in the binding.
I hope this is enough information to get an idea of the problem.
Thanks for the help
