Integer Columns in ScalaFX TableView

I am new to ScalaFX. I am trying to adapt a basic TableView example, to include Integer columns. So far, I have come up with the following code: ``` class Person(firstName_ : String, age_ : Int) { val name = new StringProperty(this, "Name", firstName_) val age = new IntegerProperty(this, "Age", age_) } object model{ val dataSource = new ObservableBuffer[Person]() dataSource += new Person("Moe", 45) dataSource += new Person("Larry", 43) dataSource += new Person("Curly", 41) dataSource += new Person("Shemp", 39) dataSource += new Person("Joe", 37) } object view{ val nameCol = new TableColumn[Person, String]{ text = "Name" cellValueFactory = {_.value.name} } val ageCol = new TableColumn[Person, Int]{ text = "Age" cellValueFactory = {_.value.age} } } object TestTableView extends JFXApp { stage = new PrimaryStage { title = "ScalaFx Test" width = 800; height = 500 scene = new Scene { content = new TableView[Person](model.dataSource){ columns += view.nameCol columns += view.ageCol } } } } ``` The problem is that, while the `nameCol` works well, the `ageCol` doesn't even compile. In the line `cellValueFactory = {_.value.age}`, I get a type mismatch error. It is expecting a `ObservableValue[Int,Int]` but getting an `IntegerProperty`. I am using ScalaFX 1.0 M2, compiled for Scala 2.10.
