问题 What is the best way to enable my webapplication to use JSF files stored in the database? I'd like to be able to dynamically (during runtime) create new JSF pages which will be made available without having to redeploy the application. So in other words: I would like to store the bigger part of my JSF pages in the database and would like JSF to use the database as a datasource for getting JSF files. I've thought long about a solution and found some possible ways. However, I haven't been able

问题 With the code below, i'm using a listener on the selectOneRadio to redirect to the page with a query string in the url. The problem is, when i get redirected, the value of newsTitle and selectedNews are null. Why is this? Is is because i'm doing a redirect using FacesContext? news.xhtml <h:outputLabel for="title" value="Title" style="font-weight: bold;"/> <p:inputText id="title" required="true" value="#{contentEditorBacking.newsTitle}" > <p:ajax event="blur"/> </p:inputText> <h:outputLabel

问题 Im using glassfish 3.0.1 and was experimenting with columnClasses in dataTable for the first time.

问题 In the composite:interface I have defined an attribute like this: <composite:attribute name="myAttribute" required="true"/> Now when I use my composite component like this, without defining any attributes: <myTag:myCC/> I would expect an error to occur. It doesn't. What could I possibly be missing? 回答1: It will only occur if your JSF project stage is set to Development as follows in web.xml : <context-param> <param-name>javax.faces.PROJECT_STAGE</param-name> <param-value>Development</param

问题 I have this simple JSF button: //Question Dialog function deletedialog(button, a){ $("<div />", { text: a }).dialog({ width: 600, buttons: { "Ok": function() { $("#form\\:deleterow").click(); // $('input[id$="deleterow"]').click(); $(this).dialog("close"); button.value = "Processing..."; button.disabled = true; }, "Cancel": function(event) { $(this).dialog("close"); event.preventDefault(); button.value = "Delete"; button.disabled = false; } } }); } <!-- hidden button --> <h:commandButton id=

问题 I have a PrimeFaces p:dataTable and enabled lazy loading by implementing a LazyDataModel . The dataTable holds search results, so when doing a search request the search service only retrieves the required (paginating) data. That works fine. When doing a ajax request with p:commandButton : <p:commandButton id="searchCmdBtn" value="Search" action="#{searchBean.search}" update=":resultForm:resultList :filterForm:filterMenu :resultForm:messages" ajax="true" /> the dataTable gets updated properly,
