    Practical Richfaces examples not working...

    Agustín Cardeilhac Banús Newbie

      Hi to all !!! I'll try to be short as here in Argentina there is too much hot... Well... As you see guys I'm reading "Practical Richfaces" by Max Katz but with many examples (mainly about updating with ajaxkeys and datatable or datagrids) I seem not to get it working... Maybe It's the scope the problem, as the book explains every java class but not give any detail about this !... Another problem is for instance, when I want to use a4j:include and a4j:keepAlive... If one of you have read this book, pls help me... As there are other frameworks but I consider richfaces really cool... and I prefer it more as there is more documentation ! Cheers

          Agustin,

           

          Can you please provide more details: what code do you use and what issues you are expecting?

            The JSP File...

            <h:form>
                        <rich:panel style="width:450px;"  >
                            <f:facet name="header">Partial update</f:facet>
                            <rich:dataGrid id="dataUser"  value="#{user.userList}" var="theUser" columns="4" border="1" ajaxKeys="#{user.rowsToUpdate}">
                                <h:panelGrid id="userinfo">
                                    <h:outputText value="#{theUser.name}" />
                                    <h:outputText value="#{theUser.email}" />
                                    <a4j:commandLink value="edit"
                                        onclick="#{rich:component('modalPanel')}.show()"
                                            reRender="edituserinfo">
                                        <f:setPropertyActionListener value="#{theUser}" target="#{user.selectedUser}" />
                                    </a4j:commandLink>
                                </h:panelGrid>
                            </rich:dataGrid>
                        </rich:panel>
                    </h:form>
            
                        <rich:modalPanel id="modalPanel">
                            <f:facet name="header">Edit</f:facet>
                            <a4j:keepAlive ajaxOnly="true"  beanName="user" />
                            <h:form>
                                <h:panelGrid id="edituserinfo" columns="2">
                                    <h:outputText value="Name:" />
                                    <h:inputText value="#{user.selectedUser.name}" />
                                    <h:outputText value="Email" />
                                    <h:inputText value="#{user.selectedUser.email}" />
                                </h:panelGrid>
                                <h:panelGrid columns="2">
                                    <a4j:commandLink value="Close"
                                        onclick="#{rich:component('modalPanel')}.hide()" />
                                    <a4j:commandLink value="Save" actionListener="#{user.updateUser}"
                                        oncomplete="#{rich:component('modalPanel')}.hide()"

                                </h:panelGrid>
                            </h:form>
                        </rich:modalPanel>
            

             

            And the Java Classess...

            "user" Bean

            import java.util.ArrayList;
            import java.util.HashSet;
            import java.util.List;
            import java.util.Set;
            import javax.annotation.PostConstruct;
            import javax.faces.bean.ManagedBean;
            import javax.faces.bean.RequestScoped;
            import javax.faces.event.ActionEvent;
            @ManagedBean(name="user")
            @RequestScoped
            public class UserBean
            {
                private List <User>userList;
                private User selectedUser;
                private Set <Integer>rowsToUpdate;
            
                @PostConstruct
                public void init ()
                {
                    userList = new ArrayList <User>();
                    for (int i=0; i<20; i++)
                    {
                        userList.add(new User("user","user@email.com"));
                    }
                    rowsToUpdate = new HashSet <Integer>();
                }
                public User getSelectedUser()
                {
                    return selectedUser;
                }
                
                public void setSelectedUser(User selectedUser)
                {
                    this.selectedUser = selectedUser;
                }
            
                public List <User> getUserList()
                {
                    return userList;
                }
            
                public void updateUser (ActionEvent event)
                {
                    rowsToUpdate.clear();
                    int index = userList.indexOf(selectedUser);
                    rowsToUpdate.add(index);
                }
            
                public Set<Integer> getRowsToUpdate()
                {
                    return rowsToUpdate;
                }
            }
            

            "userf" Bean

             

            import javax.faces.bean.ManagedBean;
            import javax.faces.bean.RequestScoped;
            
            @ManagedBean
            @RequestScoped
            /**
             *
             * @author Agustin
             */
            public class User
            {
                private String name;
                private String email;
            
                public User()
                {}
            
                public User(String name, String email) {
                    this.name = name;
                    this.email = email;
                }
            
                public String getEmail() {
                    return email;
                }
            
                public void setEmail(String email) {
                    this.email = email;
                }
            
                public String getName() {
                    return name;
                }
            
                public void setName(String name) {
                    this.name = name;
                }
            
            
            }
            

            Well If you see the images... After clicking in edit and editing the details and clicking on save, it should update only the row where I clicked... But I don't get anything updated !!!... Hope I can get help from you or from another... Hope it doesn't take too much time !!!

                He-he, good I've noticed that sometimes JSF does not redeploy changed Facelets pages in runtime - so probably this can be the cause?

                  Really don't know... But well here is a strange and weird thing that happened me often and previous before switching to this new example... I do my coding and when I try to run the project I get all the page in blank but If I remove some components, all the rest is display...

                  For instance...

                   

                  <h:form id="form">
                                                  <rich:contextMenu attached="false" id="menu" submitMode="ajax">
                                                      <rich:menuItem value="Show #{auto.marca} - #{auto.modelo}" ajaxSingle="true">
                                                          <a4j:actionparam name="det" assignTo="#{listaAutos.selected}" value="#{auto}"/>
                                                      </rich:menuItem>
                                                  </rich:contextMenu>
                  
                          <h:panelGrid columns="2">
                  
                          <rich:dataTable value="#{listaAutos.lista}" var="car" id="table" onRowMouseOver="this.style.backgroundColor='#F8F8F8'" onRowMouseOut="this.style.backgroundColor='#{a4jSkin.tableBackgroundColor}'" rowClasses="cur">
                  
                                    <rich:column >
                  
                                          <f:facet name="header">
                                              <h:outputText value="Marca" />
                                          </f:facet>
                                          <h:outputText value="#{car.marca}"/>
                  
                                    </rich:column>
                  
                                    <rich:column>
                  
                                          <f:facet name="header">
                                              <h:outputText value="Modelo" />
                                          </f:facet>
                  
                                          <h:outputText value="#{car.modelo}"/>
                  
                                    </rich:column>
                  
                                    <rich:column>
                  
                                          <f:facet name="header">
                                              <h:outputText value="Precio" />
                                          </f:facet>
                  
                                          <h:outputText value="#{car.precio}" />
                  
                                    </rich:column>
                              <rich:componentControl event="onRowClick" for="menu" operation="show">
                                  <f:setPropertyActionListener target="#{listaAutos.selected}" value="#{car}"/>
                                  <f:param value="#{car}" name="auto"/>
                              </rich:componentControl>
                  
                              </rich:dataTable>
                  
                              <a4j:outputPanel ajaxRendered="true">
                                    <rich:panel>
                                          <f:facet name="header">
                                              <h:outputText value="Last Menu Action" />
                                          </f:facet>
                                        <h:outputText value="#{listaAutos.selected.toString}"/>
                                    </rich:panel>
                              </a4j:outputPanel>
                  
                  
                        </h:panelGrid>
                                          </h:form>
                  

                  If I remove the contextmenu, the outputpanel and the rich componentcontrol the datatable is display but If I leave one of these, nothing is display... Why is happenning this ? do u know ?

                  Thankx dfor the help
