-----------------------------------

Hi Maximiliano,

I really need an example so I can debug the problem myself (not that I don't trust your debugging, but without a way to reproduce, it's very hard to tell if the bug is fixed).

> I have the following action method:
> 	public String confirm() {
> 		log.info("---------> Saving Selected Role");
> 		securityServices.confirmRole(roleOperationType, selectedRole);
> 		events.raiseTransactionSuccessEvent(Constant.REFRESH_ROLE_LIST);

> This pages config ( exception trapping only ):
> 	<!-- Exceptions Trapping -->
> 	<exception class="javax.persistence.OptimisticLockException">

> 		<redirect view-id="/pages/publicArea/errors/genericError.xhtml">
> 			<message>#{messages['dirty_data_error']}</message>

> Im testing exception handling functionality of my app. When the service of my action:
> securityServices.confirmRole(roleOperationType, selectedRole);
> throws this exception:
> javax.faces.el.EvaluationException: javax.persistence.PersistenceException: org.hibernate.PropertyValueException: not-null property references a null or transient value: com.teracode.seamapp.security.model.Role.home
> 	at javax.faces.component.MethodBindingMethodExpressionAdapter.invoke(MethodBindingMethodExpressionAdapter.java:91)
> In some cases app works fine ( closes current long-running conversation, opens error page and shows error message ) and in other cases leaves conversation open and dont show error message. I do always the same testing steps over and over .... and sometimes fails and sometimes not. I couldnt find an error criteria, but, when I change parameter concurrent-request-timeout on components.xml, setting a big value, something funny happens. 
> Imagine I set concurrent-request-timeout on ten seconds. If I execute action and app answers me instantly, app works fine. If action lasts for ten seconds, app fails. 
> I thought on sending you an example, but I've tested app at my partners machines, and ...... had the same behavior.
> Best regards
