Torsten Krah commented on SHALE-277:
------------------------------------
I would like to see this reopened.
As i wrote to the list, it does not work for me. I did integrate the use case
example in my application, but when i hit the test pages submit button - the
arithmetic exception is thrown - but a null pointer exception is thrown too,
because my FacesContext dissapeared, i don't know why its gone - but its not
there anymore after hitting the button to trigger the exception.
clay based exception trace snippet:

web.xml context param looks like this:
<context-param>
<param-name>
org.apache.shale.view.EXCEPTION_DISPATCH_PATH
</param-name>
<param-value>/jsf/error500.html</param-value>
</context-param>
The error page itself is displayed correct but empty if i call the page without
an exception, so this should not be an issue.
Any help is welcome.

> Shale is eating 500s errors
> ---------------------------
>
> Key: SHALE-277
> URL: http://issues.apache.org/struts/browse/SHALE-277
> Project: Shale
> Issue Type: Bug
> Components: Core
> Affects Versions: 1.0.3, 1.0.4-SNAPSHOT
> Environment: Tomcat 5.5.17 + Myfaces 1.1.3
> Reporter: Veit Guna
> Assigned To: Craig McClanahan
>
> When using shale-core for the s:token tag in my myfaces webapp, shale is
> eating 500 errors. That means if for example
> a Nullpointer Exception occurs, it doesn't let tomcat use the custom error
> page configured in the web.xml for 500 errors.
> If I remove shale-core from my webapp, everything works fine and the custom
> error-page is displayed.
