I am novice to javaFX, and i am working on a javaFX application. The error i got is that i am unable to fetch the child node from fxml file, The fxml file is like this

<children>
    <VBox fx:id="sideMenuVBox" alignment="TOP_CENTER" maxHeight="1.7976931348623157E308" maxWidth="1.7976931348623157E308" minHeight="600.0" minWidth="125.0">

    </VBox>
</children>
</AnchorPane>

I am getting VBox,but not any other button. Here is the corresponding controller code. public class ModifyMenu implements Initializable{

private List<String> misReportsList;
@FXML
private AnchorPane content;


public void comboOnAction()
{   

    String selectedItem=this.combo.getSelectionModel().getSelectedItem();
    List<String> resultantList;
    if(selectedItem.equals("Masters"))
    {

        resultantList=this.mastersList;
        this.vbox.getChildren().clear();

        show(resultantList);

    }

    else if(selectedItem.equals("Address Book"))
    {   
        resultantList=this.addressBookList;
        this.vbox.getChildren().clear();

        show(resultantList);
    }

    else if(selectedItem.equals("Vouchers"))
    {
        resultantList=this.vouchersList;
        this.vbox.getChildren().clear();
        show(resultantList);
    }

    else if(selectedItem.equals("Sales Purchase"))
    {
        resultantList=this.salesPurchaseList;
        this.vbox.getChildren().clear();
        show(resultantList);

                        hbox.getChildren().add(btn);

                        */
                        }
                    });
            hbox.getChildren().add(dynamicListLabel);
            hbox.getChildren().add(newNameTextField);
            hbox.getChildren().add(makeChangeButton);
            vbox.getChildren().add(hbox);

I tried many things but it only says that PArent$2 can't be cast into javafx.scene.(any).

Your content variable is an AnchorPane, so the line

((Pane) content.getChildren()).getChildren();

is wrong, since content.getChildren() returns a child list (ObservableList<Node>) and it cannot be cast to Pane.

The VBox with fx:id="sideMenuVBox" is the only child of AnchorPane. You can get it as

VBox vb = (VBox) content.getChildren().get(0);

then you can get button children of vbox by

vb.getChildren();

However, all controls in your FXML file have fx:id attribute defined. You can directly inject and access them with these ids. For more info, do research on for what fx:id is used for.
