So, I have a jar that contains several common .xhtml files that I use in my web project (JSF2.2 in a Wildfly 8.1 server) as custom components.
Also, in the same .jar I have a utility class ( ViewUtils ) that has a function that I call from the .xhtml files located in my web project.
The thing is that I actually want to access that EL function from the .xhtml files located in the same jar where the function is, and I can't. JBoss says that the EL expression is not recognized. However, I am able to call that function from the .xhtml files located in my web project (.war)
Do I explain myself?
Here is the code.
This is the code in my .jar
public final class ViewUtils {
(...)
public static String getEnumMessageKey(final Enum<?> e) {
String key = "";
try {
key = "enum_" + e.getClass().getSimpleName().toLowerCase() + '_' + e.name().toLowerCase();
} catch (Exception e) {
LOG.debug("Key not found or null.");
}
return key;
}
(...)
}
custom.taglib.xml
<namespace>http://mycompany.com/taglib</namespace>
<composite-library-name>conexiacomponent</composite-library-name>
<function>
<function-name>enum_key</function-name>
<function-class>com.mycompany.one.webcore.util.ViewUtils</function-class>
<function-signature>java.lang.String getEnumMessageKey(java.lang.Enum)</function-signature>
</function>
.xhtml component
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui"
xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:composite="http://java.sun.com/jsf/composite" xmlns:cx="http://mycompany.com/taglib">
(...)
<li>#{i18n[cx:enum_key(cc.attrs.enumParam)]}: #{cc.attrs.afiliado.numeroDocumento}</li>
(...)
</composite:implementation>
</html>
And this is a .xhtml located in my .war
<?xml version="1.0" encoding="UTF-8"?>
<!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:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui"
xmlns:cnx="http://mycompany.com/taglib"
xmlns:composite="http://java.sun.com/jsf/composite">
<composite:interface>
<composite:attribute name="valuePath"/>
<composite:attribute name="view"/>
</composite:interface>
<composite:implementation>
<h:selectOneMenu id="tipoDoc" value="#{cc.attrs.valuePath}" converter="com.mycompany.one.webcore.converter.GeneralConverter" styleClass="form-control input-sm" >
<f:selectItem itemLabel="Seleccione.." itemValue="#{null}" />
<f:selectItems value="#{comboView.documentTypes}" var="_ti" itemLabel="#{i18n[cnx:enum_key(_ti)]}" itemValue="#{_ti}" />
</h:selectOneMenu>
</composite:implementation>
</html>
And finally, this is the error that I get when I try to access a view that includes one of those jar components (that calls the function).
Caused by: javax.el.ELException: Function 'cx:enum_key' not found
Please ask me any questions if something is not clear enough.
Thanks in advance.
I solved it.
The problem didn't have anything to do with external jars or whatsoever.
In my code I was calling the function in my .xhtml like this:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui"
xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:composite="http://java.sun.com/jsf/composite" xmlns:cx="http://mycompany.com/taglib">
(...)
<li>#{i18n[cx:enum_key(cc.attrs.enumParam)]}: #{cc.attrs.afiliado.numeroDocumento}</li>
(...)
</composite:implementation>
</html>
And the EL expression should have been inside a value attribute like this:
<html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns:p="http://primefaces.org/ui"
xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:composite="http://java.sun.com/jsf/composite" xmlns:cx="http://mycompany.com/taglib">
(...)
<li><h:outputText value="#{i18n[cx:enum_key(cc.attrs.enumParam)]} #{cc.attrs.afiliado.numeroDocumento}" /></li>
(...)
</composite:implementation>
</html>
So, thanks anyway!

I'm having trouble displaying the deploy-java button on ajax rerender
<h:form id="deployJavaForm" rendered="#{myBean.shouldRender}">
<h:outputScript library="js" name="http://java.com/js/deployJava.js" target="head" />
<script type="text/javascript">
deployJava.createWebStartLaunchButton('blah.jnlp', '1.7.0');
</script>
</h:form>
when
myBean.shouldRender == true
and the form is updated the only thing being displayed (on a white page) is the deployJava-button and the request is left hanging. if shouldRender is true on the initial request, page and button is displayed correctly.
Im using primefaces in case it can help.
What I want to do is to have the button to be displayed correctly regardless if its part of a ajax rerender or a complete initial request.
Update:
I did my homework and created a minimal example that still reproduces the problem. It seems I still get the same problems regardless if script declaration is in head or in body (I have copy of deployJava.js in resources/js)

<h:outputScript>
deployJava.createWebStartLaunchButton(

edit: added picture
after click of update button, only deployJava button is rendered and page is loading
edit (daniel): both on success and oncomplete give same behaviour :(
<h:form id="djForm">
<h:outputScript>
function abcefg() {

</h:form>
Alternatively to using js and css visibility described in my comment you can write own composite button component. Using Firebug you can investigate which markup is generated by the deployJava.createWebStartLaunchButton script and add it by yourself statically. So your component could be:
<!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:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:composite="http://java.sun.com/jsf/composite">
<head>
<title>deployJava Button component</title>
</head>
<body>
<composite:interface>
<composite:attribute name="version" required="true"
type="java.lang.String" />
<composite:attribute name="url" required="true"
type="java.lang.String" />
</composite:interface>
<composite:implementation>
<a onmouseover="window.status=''; return true;"
href="javascript:if (!deployJava.isWebStartInstalled("#{cc.attrs.version}")) {if (deployJava.installLatestJRE()) {if (deployJava.launch("#{cc.attrs.url}")) {}}} else {if (deployJava.launch("#{cc.attrs.url}")) {}}"><img
border="0" src="//java.com/js/webstart.png" /></a>
</composite:implementation>
</body>
</html>
so your page will be:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

xmlns:comps="http://java.sun.com/jsf/composite/comps"
xmlns:p="http://primefaces.org/ui">
<h:head>
<!-- <script type="text/javascript" src="http://java.com/js/deployJava.js" />-->
</h:head>
<h:body>
<h:outputScript library="js" name="deployJava.js" target="head" />
<h:form id="djForm">
<comps:deployJavaButton version="1.7.0" url="test.jnlp" rendered="#{myBean.shouldRender}" />
<p:commandButton value="update" update="djForm" />
</h:form>
</h:body>
</html>
The main idea is to avoid executing button creation script twice and more.
May be using h:panelGroup instead of h:form will help. Something like that:
<h:form id="djForm">
<h:panelGroup rendered="#{myBean.shouldRender}">
<script type="text/javascript">
deployJava.createWebStartLaunchButton(
'test.jnlp', '1.7.0');
</script>
</h:panelGroup>
<p:commandButton value="update" update="djForm" />
</h:form>
I can't get the preRenderView event listener to work on a GET request in JSF 2.1.
I have found a lot about it but nothing seems to work e.g.:

Please help me figure out how to get it working..
Update 1:
I have made changes as suggested by BalusC but it is still not working..

That <f:view> isn't rightly used, it has to wrap the entire view. Remove it (JSF will implicitly create one), or at least let it wrap the entire view, including <h:head> and <h:body> tags.
By the way, the <f:event> does not need to go in a <f:metadata>. That applies only to <f:viewParam>. A <f:event> listener which depends on results of <f:viewParam> is indeed often for sole self-documentary purposes also placed in the same <f:metadata> block, but that is thus not a requirement of <f:event> itself.
In your case, it'd be easier to just put it in <ui:define name="content">.
ComponentSystemEvent seems to be missing in the method signature.
Method needs to look like this:
public void newRequest(final ComponentSystemEvent event) {
System.out.println("Someone requested me");
}
And then place a caller in the template or in the seperate views, that won't do any difference.
<f:event listener="#{userSessionAction.newRequest}" type="preRenderView"></f:event>
I ended up making a solution with a PostConstruct method in a view scope bean.
Like this: Initializng a Backing Bean With Parameters on Page Load with JSF 2.0
Bean:
#ManagedBean
#ViewScoped
public class ResultsController {
#ManagedProperty(value="#{applicationData.total}")
private int total;
#ManagedProperty(value="#{applicationData.yes}")
private int yes;
#ManagedProperty(value="#{applicationData.no}")
private int no;
#PostConstruct
public void postConstruct() {
if (getTotal() < 1) {
ExternalContext ec = FacesContext.getCurrentInstance().getExternalContext();
try {
ec.redirect(ec.getRequestContextPath() + "/noResults.jsf");
} catch (IOException e) {
System.out.println("noResults.jsf redirect failed.");
e.printStackTrace();
}
}
}
...
}
View:

I defined a composite component (actually a few) and when I try to re-render a component inserted with I get the error mentioned:
<f:ajax> contains an unknown id ':contentFrm' - cannot locate it in the context of the component j_idt40
If I simply replace:
<et:pageContent formId="contentFrm">
with
<h:form id="contentFrm">
<div>
then everything works fine
Here is the relevant code:

Some more tests.. using same component get's the same result.. for example the following code gives similar error (even replacing render="accountSummaryLines" with render=":accountSummaryLines")..

</et:pageContent>
</ui:define>

The only way I got this particular example working is using render="#form" like so..
It cannot be found because the composite component is by itself a NamingContainer. The real valid client ID would be :idOfComposite:contentFrm where idOfComposite is the (auto)generated ID of the composite component itself. If you do a View Source in webbrowser and locate the <form> in question, then you'll see it.
You need to give the composite component a fixed ID
<et:pageContent id="contentFrm">
and use exactly this ID on a plain HTML element which wraps the composite's content, e.g. <div> or <span>.
<composite:implementation>
