[jboss-user] [JBoss Seam] - javax.el.PropertyNotFoundException

Hello everyone, i've got a problem with some code (mainly copied from the booking example). I use Jboss AS 4.2.2 with SEAM 2.0.0. The Booking-Example works fine. However my own page pr_overview.xhtml: | <ui:composition xmlns="http://www.w3.org/1999/xhtml" | xmlns:s="http://jboss.com/products/seam/taglib" | xmlns:ui="http://java.sun.com/jsf/facelets" | xmlns:f="http://java.sun.com/jsf/core" | xmlns:h="http://java.sun.com/jsf/html" | xmlns:rich="http://richfaces.org/rich" template="layout/template.xhtml" | xmlns:a4j="http://richfaces.org/a4j"> | | <ui:define name="body"> | | <h:messages globalOnly="true" styleClass="message" /> | <br /> | <rich:panel> | <f:facet name="header">Probandenübersicht</f:facet> | <rich:panel> | <h:form id="searchCriteria"> | <h:panelGrid columns="4"> | <h:outputText value="Name: " /> | <h:inputText id="searchStringName" | value="#{subjectSearch.searchString}" /> | | <a4j:commandButton value="Suche" id="findSubjects" | action="#{subjectSearch.runQuery}" reRender="searchResults" /> | </h:panelGrid> | </h:form> | </rich:panel> | with the backing bean: | import java.util.List;
