Did you find an answer? i'm having the same problem. I've passed, as a request attribute, a date parameter and the link with the parameter looks like this : <a id="_id5" href="/project/personneRecherche.seam?dateNaissance=20+f%C3%A9vr.+2000&codeMorale=&prenom=&nom=&cid=7">Recherche</a> I'm in french local and the parameter value looks like "20+févr.+2000". Then i got a parse parameter error: - Exception | Exception during request processing: Unparseable date: "20 févr. 2000" | | java.text.DateFormat.parse(Unknown Source) | javax.faces.convert.DateTimeConverter.getAsObject(DateTimeConverter.java:82) | org.jboss.seam.pages.Param.getValueFromRequest(Param.java:144) | org.jboss.seam.core.Pages.applyRequestParameterValues(Pages.java:598) | org.jboss.seam.jsf.AbstractSeamPhaseListener.beforeRender(AbstractSeamPhaseListener.java:176) | org.jboss.seam.jsf.SeamPhaseListener.beforePhase(SeamPhaseListener.java:57) | org.apache.myfaces.lifecycle.PhaseListenerManager.informPhaseListenersBefore(PhaseListenerManager.java:70) | org.apache.myfaces.lifecycle.LifecycleImpl.render(LifecycleImpl.java:373) | javax.faces.webapp.FacesServlet.service(FacesServlet.java:138) | org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) | org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | org.jboss.seam.web.RedirectFilter.doFilter(RedirectFilter.java:45) | org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | org.jboss.seam.web.ExceptionFilter.doFilter(ExceptionFilter.java:57) | org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | org.ajax4jsf.framework.ajax.xmlfilter.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:75) | org.ajax4jsf.framework.ajax.xmlfilter.BaseFilter.doFilter(BaseFilter.java:213) | org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) | org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:202) | org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) | org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:213) | org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:178) | org.jboss.web.tomcat.security.SecurityAssociationValve.invoke(SecurityAssociationValve.java:175) | org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:432) | org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:74) | org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) | org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) | org.jboss.web.tomcat.tc5.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:156) | org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) | org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) | org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:869) | org.apache.coyote.http11.Http11BaseProtocol$Http11ConnectionHandler.processConnection(Http11BaseProtocol.java:664) | org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) | org.apache.tomcat.util.net.MasterSlaveWorkerThread.run(MasterSlaveWorkerThread.java:112) | java.lang.Thread.run(Unknown Source) Have any clue?
