[Building Sakai] Samigo error: Error testing property 'formatByPart' in bean of type null

[George Pipkin]

Hi Everybody -

    We have been seeing an increasing tempo of exceptions thrown by 
samigo (24 over the
pas week).  The exceptions take place when somebody is taking an 
assessment, but they
appear to happen entirely up in JSF.  Here's a piece of a typical log entry:

2011-10-03 11:32:13,563 ERROR TP-Processor27 
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/samigo-app].[sakai.samigo] 
- Servlet.service() for
servlet sakai.samigo threw exception

I'm not sure what formatByPart is.  Anybody else ever see this ?
