Hello All,
I am running the hello world faces portlet example using the MyFacesGenericPortlet class. I changed the scope for my bean to request and updated the concatenateNames() method to get the first and last name out of the context, but I am getting a class cast exception. This worked fine when it was in the session scope. I am using jboss-portal-2.2.1-SP2-bundled version of the portal. Please help.
Thanks,
Mark
faces-config.xml setting:
| <managed-bean-scope>request</managed-bean-scope>
|
jsp:
| <%@ taglib uri="http://java.sun.com/jsf/html" prefix="h" %>
| <%@ taglib uri="http://java.sun.com/jsf/core" prefix="f" %>
|
| <f:view>
| <div align="center">
| <h:form id="helloForm">
| <h:panelGrid columns="2">
| <h:outputText styleClass="portlet-font" value="First Name:"/>
| <h:inputText value="#{user.firstname}" align="center" required="true" id="firstName"/>
| <h:outputText styleClass="portlet-font" value="Last Name:"/>
| <h:inputText value="#{user.lastname}" align="center" required="true" id="lastName"/>
| </h:panelGrid>
| <br/>
| <h:commandButton action="#{user.concatenateNames}" value="Next"/>
| </h:form>
| </div>
| </f:view>
|
ConcatenateNames method:
| public String concatenateNames() {
| FacesContext context = FacesContext.getCurrentInstance();
| HttpServletRequest request = (HttpServletRequest) context.getExternalContext().getRequest();
| String firstNameConcat = request.getParameter("helloForm:firstName");
| String lastNameConcat = request.getParameter("helloForm:lastName");
|
| setFullname(firstNameConcat + " " + lastNameConcat);
| return "done";
| }
|
Exeption:
