javaFx Label wrapText doesn't work

I am new developer and I try to make a program. in my program there is a list of messages (listMessages) and each message in it is a MessageItemController which I created (a custom control) with a VBox in it that contains a label and some other things. Sudo code of that VBox in MessageItemController: 

<VBox fx:id="VBoxContent" GridPane.columnIndex="1" GridPane.rowIndex="1" GridPane.vgrow="ALWAYS">
        <children>
            <Label fx:id="lblMessage" text="message" textOverrun="CLIP" wrapText="true">
                <padding>
                    <Insets left="10.0" />
                </padding>
            </Label>
           ...
        </children>
    </VBox>

I want to VBoxContent has a maximum width. before, I set a MaxWidth for my VBoxContentto for example 300px. (I do this in scenebuilder and my fxml file not with code). It's work perfectly. all my message which I add to my listMessages work.
Now I changed my idea and I want MessageItemController to has maxWidth but 0.5 percent of its parent (I mean listMessages which I add this messages to them). so I remove maxWidth from my fxml file and add this code in my controller: 

listMessages.widthProperty().addListener((observable, oldValue, newValue) -> {
        if (observableListMessages != null)
            observableListMessages.forEach(x -> {
                x.VBoxContent.setMaxWidth(0.5 * newValue.doubleValue());                    
            });
    });

but maybe wrapText of label doesn't work if I set MaxWidth (or even PrefWidth) for my VBox from code (not fxml).
Is it possible to help my problem? If you can say how can I make text wrap or if it is not possible and it is problem of javafx so if there is any idea to achieve my purpose, please say it.
I'm sorry for bad English. Thanks.

What worked for me was:

label.setMinHeight(Region.USE_PREF_SIZE);

Wrap your text in a thing called TextFlow in your FXML. It will save you so much headaches.

You need to set the prefWidth for the Label itself.

Here is a short demo application:

public class Main extends Application {

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

    @Override
    public void start(Stage primaryStage) {

        VBox root = new VBox(5);
        root.setPadding(new Insets(10));

        Label label = new Label("This is some long text that should be wrapped.");
        label.setWrapText(true);
        label.setPrefWidth(100);

        root.getChildren().add(label);

        primaryStage.setWidth(200);
        primaryStage.setHeight(200);

        primaryStage.setScene(new Scene(root));

        primaryStage.show();
    }
}

Until you set the preferred width for your Label, it doesn't really know where you want to start wrapping.

If you want the label to wrap with the size of your VBox, you could bind the PrefWidthProperty of your Label to the WidthProperty of the VBox instead:

label.prefWidthProperty().bind(root.widthProperty());

Doing this will allow your text to fill the width of its container, but wrap if it's too long.
