trying to use reflection in 1.5.0-M2 and somehow the get doesn't compile since it expects object of type Nothing and not Transaction:

fun getProperties(t: Transaction) {
    t::class.memberProperties.forEach {
            println(it.name)
            println(it.get(t)) // gives error since it doesn't expect type Transaction 
    }
}

println((it as KProperty0<Transaction>).get())

[Peter]

Thanks, but unfortunately doesn't work. The inferred type is KProperty1<out Transaction, *>

[Peter]

not the best workaround, but what worked:

println(it.javaGetter!!(t))

Is that a regression in 1.5-M2? Can you please file a bug at http://kotl.in/issue with a self-contained sample code to reproduce?

[Youssef Shoaib [MOD]]

Try println((it as KProperty1<Transaction, Any?>).get(t)) then. You could also do a simple (t::class as KClass<Transaction>).memberProperties.forEach {...} to solve the problem from its root

[Peter]

Sorry, not sure this is a regression issue since I didn't use it before 1.5-M2 (so msot likely just a user error ;). The suggested casts also don't work.

To make the issue even more simple and reproducible:

class Person(val name:String)
val peter = Person("peter")

peter::class.memberProperties.forEach {
    it.get(peter) // doesn't compile
}

Thank you. Yes, this is an old known issue, see https://youtrack.jetbrains.com/issue/KT-16432 discussion.
