handle-errors skipped after first transformation

           Summary: handle-errors skipped after first transformation
           Product: Cocoon 2
           Version: Current CVS
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: Normal
          Priority: Other
         Component: sitemap components
        AssignedTo: [EMAIL PROTECTED]
        ReportedBy: [EMAIL PROTECTED]


I have several places in my sitemap where there are multiple transformations 
taking place (generate-->transform-->transform-->serialize), and have 
experienced random map:handle-errors behavior when exceptions occur during the 
transformation process.

I decided to do an experiment by modifying startElement in the LogTransformer 
to throw a SAXException after it was called a few times, and here is what I 
found:

If a SAXException occurs in a transformer that is located DIRECTLY AFTER the 
generator (generate-->transformThatThrowsException-->transform-->serialize),
map:handle-errors works properly.  However, if an exception occurs in a 
transformer that comes AFTER THE FIRST transformer in the sitemap (generate--
>transform-->transformThatThrowsException-->serialize),
map:handle-errors doesn't seem to be getting called at all:  only a blank html 
page gets returned to the client, even if I specify map:handle-errors to 
serialize the error as xml.  This would also explain why map:handle-errors 
works properly for all of the single-transformation parts of my sitemap.
