Subject [jira] Created: (COCOON-2179) Exception generator doesn't work properly
Date Wed, 19 Mar 2008 11:10:26 GMT
Exception generator doesn't work properly
-----------------------------------------

                 Key: COCOON-2179
                 URL: https://issues.apache.org/jira/browse/COCOON-2179
             Project: Cocoon
          Issue Type: Bug
          Components: * Cocoon Core
    Affects Versions: 2.2-dev (Current SVN)
            Reporter: Reinhard Poetz
            Priority: Blocker


I run across some obscure behaviour, when I use the exception generator: The problem is that
it only works every second request.

When it fails, following exception is thrown:

Caused by: org.apache.cocoon.ProcessingException: Generator already set. Cannot set genera
tor 'exception'
        at <map:generate type="exception"> - file:///F:/os/cocoon/trunk/blocks/cocoon-it/.
/src/main/resources/COB-INF/sitemap.xmap:211:43
        at org.apache.cocoon.components.pipeline.AbstractProcessingPipeline.setGenerator(A
bstractProcessingPipeline.java:205)

I don't remember that I have seen this with RC2. 

I added a sample to cocoon-it and a test case to cocoon-webapp (org.apache.cocoon.it.sitemap.ErrorHandlingTest).
