> Why there's no setConverter(IConverter c) just like add(IValidator v) returning the object itself?

to elaborate a little
lets say we did let you use a setter
then we have to keep a reference to the converter in the Component, so when serialized it is one more object - that almost never changes - that has to be serialized. making components session footprint even bigger.
also if we let you use a setter we have to version the changes - so thats yet another object we have to add to session (the undo object)
by making getconverter() overridible we eliminate the two scenarios above.

when a url is accessed for a page that cannot be found in the pagemap it is considered an expired page.

so basically you create a page, some time passes and that page is removed from the pagemap via the page eviction strategy. so if you go back to that page and click a link, that url will try to retrieve the page from the pagemap, and since the page cannot be found you get the page expired page.
you can set your own via Application.getApplicationSettings().setPageExpiredErrorPage()
