I see that every property of data class annotated with

@Table

should have default value, but your

value2

field doesn't have one. Maybe this is the issue? Also, https://agrosner.gitbooks.io/dbflow/content/KotlinSupport.html doesn't mention the need of

no-arg

or anything, so you should be able to skip that suggestion.

They do not mention no-arg, because all their examples have default constructor (all constructor arguments have default values, so Kotlin will generate default constructor by default)
