Modified: portal/src/java/org/apache/jetspeed/engine/servlet
ServletRequestImpl.java
Log:
implemented the setAttribute interface to automatically namespace encode jetspeed
attributes, prefixed with "org.apache.jetspeed"
so they are accessible from portlets. Accessing these attributes obiviously makes
these portlets non-portable, however it makes
creating admin and jetspeed-specific portlets much easier. For example,
LocaleSelectorPortlet now sets the prefered language for
the entire portal (only for the current user session) by accessing the the
org.apache.jetspeed.request.RequestContext attribute.
