jsf-2.2

问题 I don't understand why this piece of code is working: <h:link value="Login" rendered="#{sessionBean.userInSessionBean == null}" /> and this piece of code is not working: <a jsf:rendered="#{sessionBean.userInSessionBean == null}">Login</a> 回答1: A HTML element will only become a passthrough element if following conditions are met: There's at least one jsf:xxx attribute from http://xmlns.jcp.org/jsf namespace. There's at least one "identifying attribute" associated with a specific JSF component.

问题 Is there a database-, primefaces- and "keep-session-alive"-free solution to prevent or to handle a ViewExpiredException silently in the background while restoring the form-inputs? for example a user with a "stay logged-in cookie" would prefer not to be redirected to some kind of an error- or start-page; he fills out some form values, comes back in an hour and then, when he submits the form, the same view is re-created with its previous inputs and the submit-action of the underlying

问题 I have this fragment: <h:form id="form"> <!-- other content --> <p:panel id="panel" header="test"> <p:inputText id="input1" value="#{viewScope.prop1}" required="true" /> <p:commandButton id="button1" process="@form" update="@form @widgetVar(dialog)" oncomplete="PF('dialog').show()" value="ok" /> </p:panel> <!-- other content --> </h:form> <p:dialog id="dialog" header="dialog" widgetVar="dialog" modal="true"> <h:form id="form2"> <p:inputText id="input2" value="#{viewScope.prop1}" required=

问题 I'm executing the following jQuery function on <p:dataTable> filter (whose id is id ) that allows users to enter only digits in the filter component. $(document).ready(function() { $("#form\\:dataTable\\:id\\:filter").keydown(function(event) { //Allow: tab, escape, and enter if(event.keyCode===9||event.keyCode===27||event.keyCode===13|| //Allow: Ctrl+A, Ctrl+C (event.keyCode===65&&event.ctrlKey===true)||(event.keyCode===67&&event.ctrlKey===true)|| //Allow: home, end, left, right (event

问题 Setup: I have 2 forms A & B I have a commandLink in form A: <h:commandLink actionListener="#{homeView.selectDiv('homeUpdates')}">#{msg.homeUpdates} <f:ajax render=":B" execute="@this" /> </h:commandLink> ...which updates form B. The problem is that when I click the ajax link, it rebuilds form A as well and gets an exception from a ui:repeat I have. Is this correct behaviour? Should it rebuild form A as well? I am using JSF 2.2 and form A contains a ui:fragment=>ui:include=>ui:repeat ====

问题 Since Mojarra/JSF 2.2. it is not possible anymore to provide a custom FaceletFactory using a web.xml context parameter: <context-param> <param-name>com.sun.faces.faceletFactory</param-name> <param-value>my.faces.overrides.MyFaceletFactory</param-value> </context-param> My application provides some CMS features, including virtual host support to serve different pages (facelets) based on the currently requested domain. So http://www.domain1.com/index.xhtml returns different content than http:/

问题 I am trying to add a multiple file upload using h:inputFile . I had a quick look through the source code and it appears that it does not have the option to render multiple="multiple" . Is there a way around this without writing a custom component? If not, is there a suggested custom JSF2.2 component available that can handle multiple Ajax file uploads? Update: I have passed the multiple="multiple" using passthrough tag, but when I debugged the FileRenderer the relevant piece of code
