           Summary: NPE in
(Aggregating)FallbackSourceFactory
           Product: Lenya
           Version: 2.0
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: major
          Priority: P2
         Component: Miscellaneous
        AssignedTo: devlenya.apache.org
        ReportedBy: alexvaluadder.com


When using Cocoon from the command line to generate a static
version of a 
Lenya site, a NullPointerException is thrown from 
org.apache.lenya.cms.cocoon.source.FallbackSourceFactory.get
Source() (line 
120) and 
org.apache.lenya.cms.cocoon.source.AggregatingFallbackSource
Factory.getSource() 
(line 95).

In looking at the Cocoon CLI sources, it looks like this is
because the 
Request has a null context path. If that's correct, then NPE
is thrown because 
we try to request.getContextPath().length() without first
checking if 
request.getContextPath() might return null.
