    <p>I'm creating a project with Spring 3.2.0, PrimeFaces 3.3.1, Mojarra 2.1.11 and then Spring Security 3.1.1.</p> <p>My problem is the whenever an ajax call is fired by PrimeFaces, like for example in table pagination, the screen components are not refreshed.</p> <p><strong>EDIT #4</strong></p> <p><strong>Whenever an ajax called is fired, an error 302 is returned from the server and the page is refreshed</strong></p> <p>I think the problem is related to Spring security, this are my settings:</p> <pre><code> &lt;security:http entry-point-ref="authenticationEntryPoint" pattern="/spring/**"&gt; &lt;security:anonymous /&gt; &lt;security:http-basic /&gt; &lt;security:custom-filter position="FORM_LOGIN_FILTER" ref="authenticationProcessingFilter" /&gt; &lt;security:logout logout-url="/spring/logout" logout-success-url="/spring/login?logout=true" /&gt; &lt;security:intercept-url pattern="/spring/login" access="ROLE_ANONYMOUS,ROLE_USER,ROLE_ADMIN" /&gt; &lt;security:intercept-url pattern="/spring/logoutSuccess" access="ROLE_ANONYMOUS,ROLE_USER,ROLE_CLIENT" /&gt; &lt;security:intercept-url pattern="/spring/intro" access="ROLE_ANONYMOUS,ROLE_USER" /&gt; &lt;security:intercept-url pattern="/spring/flows/admin_main_flow/**" access="ROLE_ADMIN" /&gt; &lt;security:intercept-url pattern="/spring/flows/client_main_flow/**" access="ROLE_CLIENT" /&gt; &lt;/security:http&gt; &lt;security:http security="none" pattern="/javax.faces.resource/**" /&gt; &lt;security:http security="none" pattern="/ajax/**" /&gt; &lt;security:http security="none" pattern="/static/**" /&gt; &lt;security:http security="none" pattern="/resources/**" /&gt; </code></pre> <p>This happen just after the login so I don't think the session should be already expired.</p> <p><strong>EDIT #4 end</strong></p> <p>I stripped down the application to a minimum and tried this code:</p> <pre><code>&lt;h:form id="testAjax" &gt; &lt;h:panelGrid columns="4" cellpadding="5"&gt; &lt;h:outputLabel for="test" value="test:" style="font-weight:bold"/&gt; &lt;p:inputText id="test" value="#{testBean.test}" /&gt; &lt;p:commandButton value="Submit" update="@form"/&gt; &lt;h:outputText value="#{testBean.test}" id="display" /&gt; &lt;/h:panelGrid&gt; &lt;/h:form&gt; </code></pre> <p>note that I double checked that no forms are nested, I tried both "process" and "update" with @form or the elements id.</p> <p>What happens is that the setter of TestBean is called, the attribute setted, but then the getter is never called again to display the new value. This are the logs on server side:</p> <pre><code>org.springframework.web.servlet.DispatcherServlet - DispatcherServlet with name 'Spring MVC Dispatcher Servlet' processing POST request for [/TryAjax/spring/WEB-INF/login.xhtml] org.springframework.web.servlet.handler.SimpleUrlHandlerMapping - Mapping [/WEB-INF/login.xhtml] to HandlerExecutionChain with handler [org.springframework.web.servlet.mvc.UrlFilenameViewController@2f46ccac] and 1 interceptor org.springframework.web.servlet.mvc.UrlFilenameViewController - Returning view name 'WEB-INF/login' for lookup path [/WEB-INF/login.xhtml] org.springframework.web.servlet.DispatcherServlet - Rendering view [org.springframework.faces.mvc.JsfView: name 'WEB-INF/login';

&lt;/beans&gt; </code></pre> <p>Please if you see anything wrong or you have any idea help me, this issue is bugging me from days. Thank you!</p> <p><strong>EDIT #1</strong></p> <p>I add the code for the backing bean and the webflow code where I declare it:</p> <pre><code>public class TestBean implements Serializable { private String test = "xxx"; public String getTest() { return test; } public void setTest(String test) { this.test = test; } } &lt;view-state id="home" view="../views/adminHome.xhtml"&gt; &lt;on-entry&gt; &lt;evaluate expression="textManager.getTest()" result="viewScope.test"/&gt; &lt;/on-entry&gt; &lt;/view-state&gt; </code></pre> <p>Now this of testBean is just the simplest test case I can make that doesn't work, the main problem I have is that no ajax call works, for example pagination for tables, adding or removing or modifying an element of a datatable, tabView etc.</p> <p>I generally create the beans for the page and put them in the viewScope or flowScope, this also for lists of data coming from the database. I tryed also having the bean managed by Spring with scope Session but it doesn't work neither. Another note is that the default value display on the page correctly.</p> <p><strong>EDIT #2</strong></p> <p>using firebug and the eclipse debug i see this:</p> <p>Initial value of TestBean.test is "xxx", I change to aaa and press submit.</p> <p>An ajax post request is sent to the server:</p> <pre><code>javax.faces.ViewState e2s1 javax.faces.partial.ajax true javax.faces.partial.execu... @all javax.faces.partial.rende... testAjax testAjax:display javax.faces.source testAjax:testButton testAjax testAjax testAjax:test aaa testAjax:testButton testAjax:testButton </code></pre> <p>When the POST is sent I firt debug a call to TestBean.getTest() and then a call to TestBean.setTest("aaa") that has the correct value.</p> <p>At this point I would expect another call to TestBean.getTest() when the response is built but the call does not happens and the response does not contain the correct value but the old value "xxx".</p> <p>If now I refresh the page the getter is called and the new value "aaa" is displayed correctly.</p> <p><strong>EDIT #3</strong></p> <p>I still can sort this out. I noticed now with firebug an unexpected behaviour:</p> <p>when I click the command button 2 requests are sent to the server, a POST and a GET.</p> <p>The POST is sent first and return an error "302 Moved Temporarily", then the GET start and return a response without the updated data. Anyone knows what error 302 means in this case and what could be the cause?</p> <p>Debugging in the same way the primefaces demo only a POST request is fired that return no errors</p> <p>Thank you</p>

    3. COPlease post the contents of your Backing Bean. I suspect it is a combination of scope and the absence of an ID for your CommandButton.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
