According to the developer guide “Using Core Modules in Extensibility API Methods*”* (https://developers.suitecommerce.com/build-sustainable-and-stable-extensions.html) the “layout component” will return a console warning. Using the “simple” syntax, what is best practice to add multiple childviews to the ’Home.View”? If I follow the addChildView method outlined in the Frontend Extensibility API docs I get the console warning. https://system.netsuite.com/help/helpcenter/en_US/APIs/SuiteCommerce/Extensibility/Frontend/Layout.html

I assume you refer to this section:

This is because the layout component does not ‘own’ this parent view. Using the code in this second example will result in the following console warning:

This refers to specific scenarios where you try to use verbose syntax with the layout container that are not in its child view chain

I am

For example, you should not use Layout.addChildViews() with PDPs

Returns the warning mentioned in the help guide.

INVALID_PARAM Invoking the method "addChildViews" with an incorrect parameter: (Header.View).
It will still work but it will be deprecated in the future. Please check the documentation.

OK, well I know why it's returning the warning. It's set up to check if the view you're adding to is Backbone.View, which in your case it obviously isn't

Also the HomeSlider.View has been updated to SCView.

Also the HomeSlider.View has been updated to SCView

Not sure that's relevant.

So the warning is a SCS bug?

Hard to say. It makes sense for all the other visual components but not for layout, as one would never add a child view to Backbone.View directly. Equally, how would we expect developers to use addChildViews() with Home.View and Header.View etc?

@Steve Goldberg this is the exact code. The following throws a warning in the console. Is it possible to add child views to the existing Home.View without throwing the warning?

var layout = container.getComponent('Layout'),
	environment = container.getComponent('Environment')
	
layout.addChildViews('Home.View', {
	'HomeSlider': {
		'HomeSlider.View': {
			childViewIndex: 1,
			childViewConstructor: function intHomeSlider() {
				return new HomeSliderView({
					environment: environment
				});
			}
		}
	}
});

Yes, you use the simple syntax instead

We have added placeholders. Edited the template.

Yes it will because ALL_VIEWS will return Backbone.View
