JavaFX: no tableview content displayed

I have created a JavaFX application, I built the native package using ant, and I confused jar with proguard-4.8

In case of confusion, whether any additional settings or code changes need to be mapped to tableview in the class for data association

Solution

I'm going my own way

col.setCellValueFactory(new Callback<TableColumn.CellDataFeatures<Test,String>,ObservableValue<String>>() {
     public ObservableValue<String> call(TableColumn.CellDataFeatures<Test,String> t) {
         // t.getValue() returns the Test instance for a particular TableView row
         return t.getValue().testproperty();
         // or
         return new SimpleStringProperty(t.getValue().getMessage());
     }
  });
