问题 The TableView class of JavaFX 2.2 has a generic type S , I am wondering how one can set this from FXML? 回答1: The same happens to a ListView or ComboBox. But I think that in the FXML file you are defining the controls and you are defining a generic ListView or a ComboBox or TableView or whatever. No matter what they are going to show. So to me it makes more sense to set the generic type in the JavaFX controller class, instead of in the FXML file. Hope it helps. 回答2: FXML is dynamically loaded

I can't figure out why 80% of the time the data populates the tableView correctly and 20% of the time it doesn't.
