New Revision: 596862
URL: http://svn.apache.org/viewvc?rev=596862&view=rev

Added action mapper to mimic the webwork behavior for redirection of actions in the default namespace.
In S2, an action in the default namespace have "" being returned as the namespace, in webwork, the package name would be used.
