Hi all, I?m trying to learn Seam by following the tutorial. I followed installation instructions (http://labs.jboss.com/portal/jbossseam/gettingstarted) thoroughly and everything went on seamlessly (pun intended :-)). Registration example is working OK, EXCEPT when data don?t pass Hibernate Validator validation. If I don?t misunderstand it is supposed to redisplay the original page. Instead of that I?m getting an ugly: HTTP Status 500 - type Exception report message description The server encountered an internal error () that prevented it from fulfilling this request. exception javax.servlet.ServletException: Error calling action method of component with id _idJsp0:_idJsp4 javax.faces.webapp.FacesServlet.service(FacesServlet.java:152) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) root cause javax.faces.FacesException: Error calling action method of component with id _idJsp0:_idJsp4 org.apache.myfaces.application.ActionListenerImpl.processAction(ActionListenerImpl.java:74) javax.faces.component.UICommand.broadcast(UICommand.java:106) javax.faces.component.UIViewRoot._broadcastForPhase(UIViewRoot.java:94) javax.faces.component.UIViewRoot.processApplication(UIViewRoot.java:168) org.apache.myfaces.lifecycle.LifecycleImpl.invokeApplication(LifecycleImpl.java:343) org.apache.myfaces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:86) javax.faces.webapp.FacesServlet.service(FacesServlet.java:137) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) note The full stack trace of the root cause is available in the Apache Tomcat/5.5.20 logs. Validators ARE exacuted but I guess somebody (¿Seam?) is not catching the exception and directing JSF to the previous page to show the error messages. Instead of that the exception is being sent back to the client (brrrr!!!) I know there are more interesting examples but I would like to understand what am I doing wrong. I´ve been googling the whole afternoon but nobody seems to have noticed such behavior. Any clues will be VERY wellcome.
