How to use a FreeMarker template in a Magnolia App?

I'm using Magnolia 5.4 and have developed an app following the documentation: https://documentation.magnolia-cms.com/display/DOCS54/Apps

The app is being rendered correctly in the magnolia shell. Opening the app shows a «Hello World» message as described in the documentation: https://documentation.magnolia-cms.com/display/DOCS54/Programming+an+app#Programminganapp-MainSubApp

I've removed the unnecessary code and ended up with this:

public class HelloWorldMainSubAppViewImpl implements HelloWorldMainSubAppView {

    private VerticalLayout layout = new VerticalLayout();
    private Listener listener;

    public HelloWorldMainSubAppViewImpl() {
        layout.setMargin(true);
        layout.setSpacing(true);
        layout.addComponent(new Label("Hello World!"));
    }

    @Override
    public Component asVaadinComponent() {
        return layout;
    }
}

Instead of using the Label component I would like to use a FreeMarker template where I define a custom view.

Having read through the documentation I haven't figured out yet how to do this.

Here is the solution to my problem, based on the previous work.

This is the «EmbeddedPageSubApp» approach as described under «Custom App»

  1. Create a regular page somewhere in your navigation.

  2. Open the Configuration app, go to /modules/<APP_NAME>/apps/<APP_NAME>/subApps/main and add a url property to the mainSubApp with an absolute path to the previously created page.

  3. Change value of the class property /modules/<APP_NAME>/apps/<APP_NAME>/subApps/main to info.magnolia.ui.framework.app.embedded.EmbeddedPageSubAppDescriptor

  4. Change the value of the subAppClass property to info.magnolia.ui.framework.app.embedded.EmbeddedPageSubApp

  5. If you don't want that page to be visible restrict its access within 'superuser' group / role so that only administrators can use it.

This binds that with an iframe. You should choose a blank template since the navigation elements of the embedded page are visible within the app.

I might be wrong here but to my knowledge Freemarker is only used to create templates and unfortunately limited to it. https://documentation.magnolia-cms.com/display/DOCS60/Template+scripts

On the other hand, What you want to do is to develop your custom app and here is an example of how to do that. https://documentation.magnolia-cms.com/display/DOCS54/My+first+content+app

Also, if you are motivated to move to latest Magnolia version, you can define your custom app pretty easily using Content Types.

Hope that helps,

Cheers,
