I cannot seem to get the exception handling working even with the basic catch all in the pages.xml
<exception>
<end-conversation/>
<redirect view-id="/error.html">
<message>Catch-all exception</message>
</redirect>
</exception>
Before I add this I get the usual 500 tomcat page with the thrown exception stack printed. After adding this I get the following
javax.servlet.ServletException: Stack must not be null
org.jboss.seam.web.ExceptionFilter.endWebRequestAfterException(ExceptionFilter.java:103)
org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:73)
halvor.filter.TimerFilter.doFilter(TimerFilter.java:46)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
root cause
java.lang.IllegalArgumentException: Stack must not be null
org.jboss.seam.core.ConversationEntry.<init>(ConversationEntry.java:40)

halvor.filter.TimerFilter.doFilter(TimerFilter.java:46)
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)
The error page is just a bit of very basic html so nothing fancy to trip it up on there.
