Mendix Studio Pro can be configured to perform Strict page URL checking. When Strict page URL checking is enabled, pages that are only accessible through a page URL will also produce consistency errors for security problems (and not just pages that are accessible through navigation, pages, or microflows). By default, this is enabled in new apps. With this setting enabled, pages are checked in the same was as pages accessible via navigation. Strict page URL checking is enabled by default to increase security.
