You can obtain detailed information on how the ViewMapping system renders items and properties through JSP fragments, by setting the DefaultViewMappingFactory component’s loggingDefault property to true. In order to render an item and its properties for viewing, the DefaultViewMappingFactory performs these tasks:
Assembles custom itemViewMappings for the item to view, if any exist; otherwise, it maps to the default itemViews.
Attaches to the itemViewMappings any custom propertyViewMappings that might exist; otherwise, it uses the default propertyViewMappings.
The log file contains detailed information on this process.
