How to solve type mismatch error on event onEditCommit?

Your event handler type looks fine to me. My guess is the type mismatch is occurring elsewhere.

Sample

Here is a sample which demonstrates setting a commit event handler when using FXML. Apologies for the verbosity, that's just how FXML is.

The edit commit handler in the sample is:

@FXML
void commitValue(TableColumn.CellEditEvent<Singular, String> event) {
    System.out.println("Commit: " + event.getNewValue());
}

where Singluar is just the name of the record class used in the TableView for the sample.

commit/CommitController.java

import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
import javafx.fxml.FXML;
import javafx.scene.control.TableColumn;
import javafx.scene.control.TableView;
import javafx.scene.control.cell.PropertyValueFactory;
import javafx.scene.control.cell.TextFieldTableCell;

public class CommitController {

    @FXML
    private TableView<Singular> table;

    @FXML
    private TableColumn<Singular, String> value;

    @FXML
    void commitValue(TableColumn.CellEditEvent<Singular, String> event) {
        System.out.println("Commit: " + event.getNewValue());
    }

    public void initialize() {
        value.setCellFactory(TextFieldTableCell.forTableColumn());
        value.setCellValueFactory(new PropertyValueFactory<>("value"));
        value.setEditable(true);

        table.getItems().setAll(
                new Singular("enie"),
                new Singular("meenie"),
                new Singular("minie"),
                new Singular("moe"),
                new Singular("just commit!")
        );
        table.setEditable(true);
    }

    public static class Singular {
        private StringProperty value = new SimpleStringProperty();

        public Singular(String value) {
            this.value.setValue(value);
        }

        public StringProperty valueProperty() {
            return value;
        }
    }
}

commit/CommitmentApp.java

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

import java.io.IOException;

public class CommitmentApp extends Application {

    @Override
    public void start(Stage stage) throws IOException {
        stage.setScene(new Scene(createContent()));
        stage.show();
    }

    private Parent createContent() throws IOException {
        FXMLLoader loader = new FXMLLoader();

        return loader.load(
            getClass().getResourceAsStream("commit.fxml")
        );
    }

    public static void main(String[] args) {
        launch(args);
    }
}

commit.fxml

<?import javafx.scene.control.TableColumn?>
<?import javafx.scene.control.TableView?>
<TableView fx:id="table" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="130.0" prefWidth="113.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="commit.CommitController">
  <columns>
    <TableColumn fx:id="value" onEditCommit="#commitValue" prefWidth="85.0" text="C1" />
  </columns>
</TableView>

I made these changes. in EditingCell.java

public class EditingCell extends TableCell<Record, String> {

in EditController.jva added just TableColumn

public void columnEdit(TableColumn.CellEditEvent<Record,String> event)
