问题 So we have an f:event: <f:metadata> <f:event type="preRenderView" listener="#{dashboardBacking.loadProjectListFromDB}"/> </f:metadata> Which is triggered as desired on initial page load (render). However this preRenderView event is also triggered by an ajax partial page render, which re-renders an h:panelgroup with the id projectListing, as below. <h:commandButton action="#{mrBean.addProject}" value="Create Project" title="Start a new project"> <f:ajax render="projectListing" /> </h

问题 I've searched the Internet and I cannot find a list of <p:ajax> events. Can anyone provide a complete list of events for the <p:ajax> tag? I'm particularly interested if there is an onblur event or something similar. 回答1: You can search for "Ajax Behavior Events" in PrimeFaces User's Guide, and you will find plenty of them for all supported components. That's also what PrimeFaces lead Optimus Prime suggest to do in this related question at the PrimeFaces forum <p:ajax> event list? There is no

问题 We have a data table as shown in the image. There are 3 frozen columns and rest scrollable. The frozen columns are misalligned as shown. If frozen columns attribute is removed, the table looks properly. Any suggestions to solve the problem. 回答1: I have had similar issues in the past with frozen datatable and using many different scripts across different posts I have found the below script works in ALL browsers and does not require you to set a height it will calculate it. As an added bonus it

问题 I have use case in which I have to use resource bundle to display various texts on UI. Some of these resource bundle entries take paramets (e.g. {0}), for these I use h:outputFormat but sometimes that isn't enough. e.g. someMessage=Display this message with param {0} in a resource bundle. To display it on xhtml I normally do: <h:outputFormat value="#{msg['someMessage']}"><f:param value="#{someBean.value}"/></h:outputFormat> That works well when it's a simple case, but for more complex use

问题 I created my hello world JSF project, but when I deploy to Tomcat 7, I get this exception: java.lang.IllegalStateException: Could not find backup for factory javax.faces.context.FacesContextFactory. at javax.faces.FactoryFinder$FactoryManager.getFactory(FactoryFinder.java:1135) at javax.faces.FactoryFinder.getFactory(FactoryFinder.java:379) at javax.faces.webapp.FacesServlet.init(FacesServlet.java:350) at org.apache.catalina.core.StandardWrapper.initServlet(StandardWrapper.java:1284) at org

问题 I am trying to put versioning around the resources in an application. If I do like this resources/js/1_0_0/mainscript.js It does not work. It says RESOURCE_NOT_FOUND but when I do like this resources/js/mainscript.js/1_0_0.js It works. I do not like the way it is organized in the second way. First one looks cool. Any Idea? I am using Tomcat 7.0, JSF 2.0.9 Update: I was checking primefaces-2-2.1.jar. Since when I checked the page source, I saw this /javax.faces.resource/jquery/jquery.js.xhtml

问题 In JSF, <ui:repeat/> and similar components such as PrimeFaces <p:dataTable/> generate dynamic ids for sub-components based on the iteration index, i.e.: <p:dataTable id="table" var="item" value="#{itemList}"> <h:outputText id="name" value="#{item.name}"/> </p:dataTable> will generate something like this: <table id="table"> <span id="table:0:name">name0</span> <span id="table:1:name">name1</span> <span id="table:2:name">name2</span> ... <span id="table:n:name">nameN</span> </table> so all the

问题 This is basically an extension to this answer. I am trying to get an argument into a method/action call (for a delete button in a list/data table). Client: <ui:include src="..."> <ui:param name="acceptButtonBean" value="#{repoHome}" /> <ui:param name="acceptButtonAction" value="removeIndividualDocument(#{doc.id})" /> </ui:include> Sub view: <h:commandButton value="Continue" action="#{acceptButtonBean[acceptButtonAction]}" /> ... </h:commandButton> However, JSF fails with an exception saying:
