Mapping List<String> to List<Enum> fails #185

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I can't find a place to submit issues on the GitHub page, so I'll have to do it 
here. I'm using 1.4.5.
I have a list of Enum Values (Strings) in one class and I want to map them to a 
list of Enums in another class.

What steps will reproduce the problem?
1. Create an enum called EnumTest, add "foo" and "bar" as enums.
2. Create a class called Class A, add List<String> enumTest as a property
3. Create an instance of Class A, add String values for "foo" and "bar" to 
enumTest.
4. Create a class called Class B, add List<EnumTest> enumTest as a property
5. Attempt to map an instance of Class A to Class B them with orika (without a 
custom converter):
mapperFactory.registerClassMap(mapperFactory.classMap(A.class, 
B.class).byDefault().toClassMap())

What is the expected output? What do you see instead?
I expect it to map without an issue. Instead, I get this error:
Error: java.lang.ClassCastException: EnumTest cannot be cast to java.lang.String
ma.glasnost.orika.MappingException: java.lang.ClassCastException: 
com.commercehub.eeprom.restservice.model.awareness.NotificationFrequency cannot 
be cast to java.lang.String

Eh, well, I attempted to manually replace my classes with EnumTest in the error 
message. Didn't work out so well. I can provide further documentation if needed.
