Tornadofx: Code from guide not compiling

[leder11011]

Hi,

when executing the class Person.kt from the guide:

package de.auticon.maven.tornadofx

import javafx.beans.property.SimpleIntegerProperty
import javafx.beans.property.SimpleObjectProperty
import javafx.beans.property.SimpleStringProperty
import java.time.LocalDate
import java.time.Period

class Person(id: Int, name: String, birthday: LocalDate) {
val idProperty = SimpleIntegerProperty(id)
var id by idProperty

val nameProperty = SimpleStringProperty(name)
var name by nameProperty

val birthdayProperty = SimpleObjectProperty(birthday)
var birthday by birthdayProperty

val age: Int get() = Period.between(birthday, LocalDate.now()).years
}

I get the errors:

[INFO] ------------------------------------------------------------------------

You need to import tornadofx.* :)

You're welcome :) I've updated the guide to include the import.

BTW issue #677 is not resolved in the guide yet...

Done. There are too many readonlyColumn examples in the guide to my liking, I'd like to make most of them based on observable properties, since that's the best practice.
