When this code was written, it did not include an internal URL mapper and each page was loaded by a PHP script. The internal URL was a recent, mostly unfinished addition. Base URL is now supported: * for views, when they implement the BaseURLAware interface (a base class that does what most views will do with that is provided - BaseURLAwareView), * in the menu, * in form actions, * in boxes (for buttons, and for the contents if the inner view implements BaseURLAware).
