It seems the exception "Failed to invoke.." is thrown from in org.zkoss.zk.ui.util.Configuration

http://grepcode.com/file/repo1.maven.org/maven2/org.zkoss.zk/zk/5.0.0.RC/org/zkoss/zk/ui/util/Configuration.java

..and more precisely..

try {

	final EventThreadCleanup cleanup = (EventThreadCleanup)klass.newInstance();
	cleanup.cleanup(comp, evt, errs);
	cleanups.add(cleanup);
} catch (Throwable t) {

	if (errs != null) errs.add(t);

	if (!silent)
		log.error("Failed to invoke "+klass, t);
            }

Something must go wrong when executing "cleanup.cleanup(comp, evt, errs);" for a thread where a WrongValueException earlier has been thrown. Any ideas?

(Ok sorry yes the link above to grepcode was to an earlier version. The code snipped in question is however to be found in the same class in the latest release of zk which I utilize in my project.)

I utilize zk 5.0.6 with zkspring 3, that is the latest versions. I also tried zk 5.0.7 freshly without overcoming the experienced issue.
I might add that Firefox shows the errorbox one first time upon throwing WrongValueException (after reloading the same page it is however never shown again for the exception in question). In Internet Explorer it never seems to show up, even after a fresh restart of Tomcat.

I tried downloading and readding all jar files for spring, hibernate, zk, zk-spring-core, zk-spring (with dependencies) but no. The issue remains.

And a thrown WrongValueException still results in SEVERE: Failed to invoke class org.zkoss.spring.security.ui.ZkExceptionTranslationListener as well as no error pop-up box in GUI (except for the first time after a server restart when loading page in Firefox, any reloading of page or attempt to trigger event where exception is thrown from client in Internet explorer will fail).

Help!

Ok so now I've posted the issue to ZK Spring issue tracker with ID: 3240863 as well as uploaded an example project available for download to reproduce the issue.

https://sourceforge.net/tracker/?func=detail&aid=3240863&group_id=152762&atid=785191


To download example project for easy reproduction of the issue (open index.zul after having loaded the entire dynamic web app in Tomcat)
http://tinyurl.com/67zvrjg

Note: the download is an archive-RAR file of approx 59 MiB (the larger size is due to all jars included). Simply extract the folder in your Eclipse workspace, then import it as a project (dynamic web proj) and have it added to a Tomcat 7 server.

Let me know if you're looking at the issue or have any input / updates..


Best regards,
Juwian
