Griffon : How to open a new window from main view?

Question

I am new to griffon and trying to develop a griffon app. I want to open secondary window from main window. When the "next" button clicked the secondary window should be open.

config.properties

application.title = Installation Wizard

application.startupGroups = mainWindow

application.autoShutdown = true

mvcGroups.mainWindow.model = com.install.gui.MainGuiModel

mvcGroups.mainWindow.view = com.install.gui.MainGuiView

mvcGroups.mainWindow.controller = com.install.gui.MainGuiController

mvcGroups.secondaryWindow.model = com.install.gui.SecondaryGuiModel

mvcGroups.secondaryWindow.view = com.install.gui.SecondaryGuiView

mvcGroups.secondaryWindow.controller = com.install.gui.SecondaryController

MainGuiController.java:

@ArtifactProviderFor(GriffonController.class)
public class MainGuiController extends AbstractGriffonController {

    private MainGuiModel model;

    public void setModel(MainGuiModel model) {

        this.model = model;

    }

    @Threading(Threading.Policy.INSIDE_UITHREAD_ASYNC)

    public void click() {

        model.setClickCount(model.getClickCount() + 1);

        getApplication().getWindowManager().show("secondaryWindow");

    }

}

the click method is fired when I clicked next button. The click count label is increased. But the second line which is used to open the secondary window is not working.

You must create an instance of the secondaryWindow MVCGroup first. Assuming that SecondaryWindowView defines a Stage/Window that's attached to the WndowManager using the window name secondaryWindow then the following should work

public void click() {
    createMVCGroup("secondaryWindow");
    getApplication().getWindowManager().show("secondaryWindow");
}
