Subject Re: Maximum number of tokens in pageFlowScope
Date Tue, 27 May 2008 19:34:49 GMT
The source code is wrong so please log a JIRA ticket.  Process Scope was 
the name of page flow scope before oracle donated the code to apache.  
Obviously somebody forgot to change the source to match the new name 
used in the documentation.  :)  Shows how often that setting is used.
