我正试图在JRE 8中显示一个标签,说明所有内容都是正确的3秒,因为我无法在JRE 7中使用DatePicker而且我发现了这个错误.

    Exception in thread "Timer-2" java.lang.IllegalStateException: Not on FX application thread; currentThread = Timer-2

correct是一个标签,我显示3秒,它失败,correct.setVisible(false);这是第221行

    correct.setVisible(true);
    timer.schedule(new TimerTask() {
    @Override
        public void run() {
        correct.setVisible(false);
    }
    }, 3*1000);

我正在尝试将ComboBox放在表格单元格中,但我不能.代码是下一个:

private void cargaTablaDesglose() {
    TableColumn<Map, String> column1 = new TableColumn<>(Desglose1);
    TableColumn<Map, String> column2 = new TableColumn<>(Desglose2);
    TableColumn<Map, String> column3 = new TableColumn<>(Desglose3);

    column1.setCellValueFactory(new MapValueFactory(Desglose1));
    column1.setMaxWidth(0);
    column2.setCellValueFactory(new ComboBoxTableCell.forTableColumn(null));
    column2.setPrefWidth(150);
    column3.setCellValueFactory(new MapValueFactory(Desglose3));
    column3.setPrefWidth(250);

    if (CUOD.modifyData()) {
        column2.setOnEditCommit((TableColumn.CellEditEvent<Map, String> t) -> {
            actualizaObra(t.getRowValue(), t.getNewValue());
        });
            }

    tablaDesglose.getItems().clear();
    tablaDesglose.setEditable(true);
    tablaDesglose.getSelectionModel().setSelectionMode(SelectionMode.MULTIPLE);
    tablaDesglose.getSelectionModel().setCellSelectionEnabled(false);
    tablaDesglose.getColumns().clear();
    tablaDesglose.getColumns().addAll(column1, column2, column3);

    Callback<TableColumn<Map, String>, TableCell<Map, String>> cellFactoryMap
            = CUCF.getFactoryMap();
    column1.setCellFactory(cellFactoryMap);
    column2.setCellFactory(cellFactoryMap);
    column3.setCellFactory(cellFactoryMap);
}

它说无法找到forCableColumn方法的ComboBoxTableCell
