BatchUpdateStatement results in IllegalStateException: Table.columnName is already initialized

[jon-mey]

Based on this example I'm trying to get a BatchUpdateStatement to work:

Database.connect("jdbc:h2:tcp://localhost/~/h2/test", "org.h2.Driver", "sa")

...

transaction {
    addLogger(StdOutSqlLogger)

    BatchUpdateStatement(Areas).apply {
        listOf(1, 2).forEach {
            addBatch(EntityID(it, Areas))
            this[Areas.networkType] = it.toString()
        }
    }.execute(this)
}

...

object Areas : IntIdTable() {
    val latitude = double("latitude")
    val longitude = double("longitude")
    val accuracy = float("accuracy")
    val performance = double("performance")
    val networkType = text("networkType")
}

However, on the second iteration of the loop IllegalStateException is thrown:

Exception in thread "main" java.lang.IllegalStateException: Areas.networkType is already initialized

Am I doing something wrong here?
