Visual Merchandising requires a default preview URL that includes no $[template.url] properties. Specify a default preview URL with the properties of the /atg/dynamo/service/preview/PreviewURLManager component.

The defaultNoAssetPreviewURL property specifies the preview URL that is used when a merchandiser clicks the Layout button in Merchandising when no asset is currently loaded in the Details pane. For example, if a merchandiser starts a Merchandising project and immediately clicks the Layout button, the defaultNoAssetPreviewURL is displayed. This URL should not contain any asset-specific parameters. It is a good idea to specify a URL that points to the home page of the preview site.

If the defaultNoAssetPreviewURL property is not set, the default preview URL is specified by the defaultPreviewURL property. If neither property is set, the default preview URL is the first URL in the previewURLs list that does not include a $[template.url] property.
