Hello folks. Have anybody used Room with Kotlin?
I have a problem using type converters to parse list of enums.
Here are classes that I use: https://gist.github.com/zamahaka/584963739a010842dfee90a545e34d1d
This is the build failure: http://joxi.ru/RmzZPQWTWzv6lm

Have anybody encounter same problem?

[yuriy.stetsyk]

Well, manage to figure it out.
This is new User class https://gist.github.com/zamahaka/23cc8f3f8528ff867b84ecde49ef8241
and type converters
https://gist.github.com/zamahaka/f4928d3ad959b423ba40021d07f9d7a7

Found this solution after digging generated User.java class. Property 'types' has type of java.util.List<? extends UserType> when 'types' has type of List<UserType> in *.kt file.
After switching ti MutableList<UserType> everything compiles, at least 😀 .

Maybe the @JvmSuppressWildcards annotation on the type parameter would also work, then

Yeah, @JvmSuppressWildcards works. Didn't test for CRUD, but it compiles.
