1. Re: How to catch javax.faces exceptions with Seam Catch
There some text missing :-)
But looking into the server log we found that the real reason was a OptimisticLockException thrown just before.
As you can see it is wrapped within a JSF EvaluationException and that seems to be the problem.
How can a catch the exceptions produced within a JSF call? Especially I'd like to handle the OptimisticLockException to give the user a hint of what has happened.09:35:09,159 ERROR [org.jboss.as.ejb3.tx.CMTTxInterceptor]

2. Re: How to catch javax.faces exceptions with Seam Catch
Our Exception handler class looks like this. As you can see there is a default handler for Throwable, thus everything should get caught and handled.
@HandlesExceptions public class DevaExceptionHandler { @Inject private LogoutController _logoutController; @Inject private Logger _log; @Inject private FacesContext _facesContext; @Inject private Debug _debug; @PersistenceContext private EntityManager _entityManager; // Das ist zwar nicht ganz korrekt, aber ohne logout bleibt die Exception hängen public void lazyInitializationHandler(@Handles final CaughtException<LazyInitializationException> event) { _log.warn("Exception handled by lazyInitializationHandler", event.getException()); redirect(DevAViewConfig.URL_VIEW_EXPIRED); setHandled(event); clearCache(); _logoutController.logout(); } public void transactionBugHandler(@Handles final CaughtException<IllegalStateException> event) { _log.warn("Exception handled by transactionBugHandler", event.getException()); if (event.getException().getMessage().startsWith("BaseTransaction.checkTransactionState")) { redirect(DevAViewConfig.URL_VIEW_EXPIRED); setHandled(event); clearCache(); _logoutController.logout(); } } public void viewExpiredHandler(@Handles final CaughtException<ViewExpiredException> event) { _log.warn("Exception handled by viewExpiredHandler", event.getException()); redirect(DevAViewConfig.URL_VIEW_EXPIRED); setHandled(event); clearCache(); _logoutController.logout(); } public void optimisticLockHandler(@Handles final CaughtException<OptimisticLockException> event) { _log.warn("Exception handled by optimisticLockHandler", event.getException()); redirect(DevAViewConfig.URL_OPTIMISTIC_LOCK); clearCache(); setHandled(event); } public void throwableHandler(@Handles final CaughtException<Throwable> event) { final long bugId = System.currentTimeMillis(); final Throwable exception = event.getException(); final String stackTrace = getStackTrace(exception); _log.error("Bug-Id:" + bugId + ": Error occured handled by throwableHandler", exception); _debug.setCurrentBugId(bugId); _debug.setStackTrace(stackTrace); redirect(DevAViewConfig.URL_ERROR); setHandled(event); } private String getStackTrace(final Throwable exception) { final StringWriter out = new StringWriter(); ExceptionUtils.printRootCauseStackTrace(exception, new PrintWriter(out)); final String stackTrace = out.toString(); return stackTrace; } private void setHandled(final CaughtException<? extends Throwable> event) { event.unmute(); event.handled(); } private void clearCache() { try { final Cache cache = _entityManager.getEntityManagerFactory().getCache(); if (cache != null) { cache.evictAll(); _log.info("Cache cleared"); } else { _log.warn("No cache configured!"); } } catch (final Throwable e) { _log.warn("Could not clear cache", e); } } private void redirect(final String viewId) { try { // facesContext.getExternalContext().responseReset(); _facesContext.getExternalContext().redirect(viewId); } catch (final IOException e) { _log.warn("Redirect failed", e); } } }Cheers

3. Re: How to catch javax.faces exceptions with Seam Catch
It looks like you're using AS 7.0.2, correct? Which version of Seam Faces are you using? If it's not one of the more current 3.1.0 Beta versions, please try that. Also debug CatchExceptionHandler, see if the exception goes through that, if it doesn't (even when using a more current version of Seam Faces) please create a JIRA and attach a simple war (or arquillian test) that demonstrates this error. Thanks!
