Gluon mobile TextArea soft keyboard issue

Question

I'm working with a multiple view project with FXML, generated by the Gluon plugin for IntelliJ.

I added a view (scan view) next to the generated primary and secondary view and provided code for navigation in the GluonApplication class.

The first time I navigate to scan view, a carret blinks in the textarea but the soft keyboard on my android device is not shown. When I navigate to another view the keyboard briefly shows itself and disappears after a second. Then when I navigate back to scan view, the soft keyboard does show. And finally, when I retract focus from the textarea with the back button on my android device, it's not possible to regain focus by tapping the textarea.

Any info welcome, cheers.

GluonApplication.java:

public class GluonApplication extends MobileApplication {

    public static final String PRIMARY_VIEW = HOME_VIEW;
    public static final String SECONDARY_VIEW = "Product View";
    public static final String SCAN_VIEW = "Scan View";
    public static final String MENU_LAYER = "Side Menu";

    @Override
    public void init() {
        //Add views.
        addViewFactory(PRIMARY_VIEW, () -> (View) new PicklistView().getView());
        addViewFactory(SECONDARY_VIEW, () -> (View) new ProductView().getView());
        addViewFactory(SCAN_VIEW, () -> (View) new ScanView().getView());

        //Navigation side bar configuration.
        NavigationDrawer drawer = new NavigationDrawer();
        NavigationDrawer.Header header = new NavigationDrawer.Header("Gluon Mobile",
                "Multi View Project",
                new Avatar(21, new Image(GluonApplication.class.getResourceAsStream("/icon.png"))));
        drawer.setHeader(header);

        final Item primaryItem = new Item("Picklist", MaterialDesignIcon.HOME.graphic());
        final Item secondaryItem = new Item("Product", MaterialDesignIcon.DASHBOARD.graphic());
        final Item scanItem = new Item("Scan", MaterialDesignIcon.DASHBOARD.graphic());
        drawer.getItems().addAll(primaryItem, secondaryItem, scanItem);

        drawer.selectedItemProperty().addListener((obs, oldItem, newItem) -> {
            hideLayer(MENU_LAYER);
            if (newItem.equals(primaryItem)) {
                switchView(PRIMARY_VIEW);
            } else if (newItem.equals(secondaryItem)) {
                switchView(SECONDARY_VIEW);
            } else {
                switchView(SCAN_VIEW);
            }
        });

        addLayerFactory(MENU_LAYER, () -> new SidePopupView(drawer));
    }

This was a known issue, but it seems it was only fixed for TextFields: https://bitbucket.org/javafxports/8u-dev-rt/commits/ef07043d5739ace78568f20d7bc89ba0cf60c4e0

I've just created a pull request that will fix this issue for TextArea as well: https://bitbucket.org/javafxports/8u-dev-rt/pull-requests/5/fix-jfxport-41/diff

The new release of JavaFXPorts (version 8.60.7) is planned to be created somewhere next week. These fixes are included in JavaFXPorts 8.60.7, which was released on March 31, 2016 .
