Unable to create entity with overridden equals method due to field initialization error

[dannyim]

The code below works on version 0.13.7:

object Cats: IntIdTable() {
    val name = varchar("name", 64)
}

class Cat(id: EntityID<Int>): IntEntity(id) {
    companion object : IntEntityClass<Cat>(Cats)
    var name by Cats.name

    override fun equals(other: Any?): Boolean {
        if(other == null) {
            return false
        }
        return if(other is Cat) {
            name == other.name
        } else {
            false
        }
    }
}

fun main(args: Array<String>) {
    Database.connect("jdbc:h2:mem:test", driver = "org.h2.Driver")

    transaction {
        SchemaUtils.create(Cats)
        val cat = Cat.new(1) {
            name = "Hamilton"
        }
    }
}

But after updating to 0.21.1 I am getting the following error:

Exception in thread "main" java.lang.IllegalStateException: com.example.Cats.name is not initialized yet

Within EntityClass.kt I see:

    internal open fun invalidateEntityInCache(o: Entity<ID>) {
        val entityAlreadyFlushed = o.id._value != null
        val sameDatabase = TransactionManager.current().db == o.db
        if (entityAlreadyFlushed && sameDatabase) {
            val currentEntityInCache = testCache(o.id)
            if (currentEntityInCache == null) {
                get(o.id) // Check that entity is still exists in database
                warmCache().store(o)
            } else if (currentEntityInCache != o) {
                exposedLogger.error("Entity instance in cache differs from the provided: ${o::class.simpleName} with ID ${o.id.value}. Changes on entity could be missed.")
            }
        }
    }

So this appears to be happening due to the newly created entity being compared to a cached instance. Since this is a newly created entity, why would the cache invalidation be performed?

Fixed in master. Will be available in 0.22.1

I am still having this issue with 0.29.1:

UserSubscriptions.user_id is not initialized yet
