Problem with h:form and p:ajax (Mojarra 2.0.2 and Primefaces 2.0.2)
I have got this site:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.prime.com.tr/ui">
<h:head></h:head>
<h:body>
<h:form id="form-some">
<h:inputText id="copingFilePhaseFocus">
<p:ajax event="focus" actionListener="#{installationController.startCopyingWarFile}" />
</h:inputText>
</h:form>
</h:body>
</html>
And backing bean:
@ManagedBean(name = "installationController")
@SessionScoped
public class InstallationController implements IPluginInstallationListener {
// Some methods here (...)
public void startCopyingWarFile(ActionEvent event) {
System.out.println("\n\n\n\nStarted\n\n\n\n");
}
}
This code was working under MyFaces 2.0.0. But under MyFaces 2.0.2 or Mojarra 2.0.2 does not. By telling "does not work" I mean that clicking (focusing) input text does not triggering actionListener (Text "Started" does not appear on standard output). Has anybody similar problem ?
EDIT 1 (After changing p:ajax to f:ajax):
<p:outputPanel id="copingFilePhase">
<p:accordionPanel speed="0.2"
rendered="#{plugin开发者_运维问答InstallerWebBean.copingFilePhase}">
<p:tab
title="#{msg['installPlugin.copyingWar']} ... #{pluginInstallerWebBean.copingFilePhaseState}">
<h:form prependId="false">
<p:focus for="copingFilePhaseFocus" />
<h:inputText id="copingFilePhaseFocus"
rendered="#{pluginInstallerWebBean.copingFilePhaseFocus}"
style="display:none;">
<f:ajax event="focus"
render="copingFilePhase obtainingPluginInformationPhase"
listener="#{installationController.startCopyingWarFile}" />
</h:inputText>
</h:form>
#{msg['installPlugin.copyingWarDescription']}
</p:tab>
</p:accordionPanel>
</p:outputPanel>
<p:outputPanel id="obtainingPluginInformationPhase">(...)</p:outputPanel>
And the error is:
javax.faces.FacesException: contains an unknown id 'copingFilePhase' - cannot locate it in the context of the component copingFilePhaseFocus
This can have two causes:
The Primefaces resource servlet is not properly configured which will cause that the necessary JavaScripts won't be loaded. You should be able to see it by checking the JS error console in your webbrowser for any JS errors when focusing the input. In Firefox, the console is available by pressing Ctrl+Shift+J.
The resource servlet will be loaded automatically in Servlet 3.0 environments (Glassfish v3, Tomcat 7, JBoss 6, etc), however in older environments, you need to configure it manually in
web.xml:<servlet> <servlet-name>PrimeFaces Resource Servlet</servlet-name> <servlet-class>org.primefaces.resource.ResourceServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>PrimeFaces Resource Servlet</servlet-name> <url-pattern>/primefaces_resource/*</url-pattern> </servlet-mapping>The method signature is wrong. You should be able to see it by reading the server logs and seeing a
javax.el.MethodNotFoundExceptionin the logs. The code example in your question is correct, but there's ambiguity inActionEvent. There's a class with the same name injava.awt.eventpackage. You might have accidently (auto-)imported it. Verify if it is indeedjavax.faces.event.ActionEventand not something else.
If none helps, you may want to consider to replace the PrimeFaces p:ajax by the standard JSF 2.0 f:ajax:
<f:ajax event="focus" listener="#{installationController.startCopyingWarFile}" />
with
public void startCopyingWarFile(AjaxBehaviorEvent event) {
// ...
}
where AjaxBehaviorEvent is javax.faces.event.AjaxBehaviorEvent.
