Javafx: TextField focus lost - javafx

Question

as the title says:
I have a TextField in a CustomMenuItem and the TextField always lost the focus on minimal mouse movement because of the onHover from the MenuItem. In the Source Code from the API i see a protected setHover Method in MenuBarSkin :(
Example:
Main.java
public class Main extends Application {
#Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
sample.fxml
<BorderPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.121" xmlns:fx="http://javafx.com/fxml/1">
<top>
<MenuBar BorderPane.alignment="CENTER">
<menus>
<Menu mnemonicParsing="false" text="File">
<items>
<MenuItem mnemonicParsing="false" text="Close" />
</items>
</Menu>
<Menu mnemonicParsing="false" text="Edit">
<items>
<MenuItem mnemonicParsing="false" text="Delete" />
</items>
</Menu>
<Menu mnemonicParsing="false" text="Help">
<items>
<MenuItem mnemonicParsing="false" text="About" />
<CustomMenuItem mnemonicParsing="false" text="Unspecified Action">
<content>
<HBox>
<children>
<Label text="Label" />
<TextField text="Test" />
</children>
</HBox>
</content>
</CustomMenuItem>
</items>
</Menu>
</menus>
</MenuBar>
</top>
</BorderPane>

Ok, i got it:
Its a bit dirty...
Controller.java
public class Controller implements Initializable{
#FXML
TextField txtField;
#Override
public void initialize(URL location, ResourceBundle resources) {
txtField.setOnMouseMoved(event -> {
txtField.requestFocus();
});
}
}
sample.fxml
<BorderPane fx:controller="Controller" maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/8.0.121" xmlns:fx="http://javafx.com/fxml/1">
<top>
<MenuBar BorderPane.alignment="CENTER">
<menus>
<Menu mnemonicParsing="false" text="File">
<items>
<MenuItem mnemonicParsing="false" text="Close" />
</items>
</Menu>
<Menu mnemonicParsing="false" text="Edit">
<items>
<MenuItem mnemonicParsing="false" text="Delete" />
</items>
</Menu>
<Menu mnemonicParsing="false" text="Help">
<items>
<MenuItem mnemonicParsing="false" text="About" />
<CustomMenuItem mnemonicParsing="false" text="Unspecified Action">
<content>
<HBox>
<children>
<Label text="Label" />
<TextField fx:id="txtField" text="Test" />
</children>
</HBox>
</content>
</CustomMenuItem>
</items>
</Menu>
</menus>
</MenuBar>
</top>
</BorderPane>
