Pass Argument to a composite-component action attribute

阅读更多关于 Pass Argument to a composite-component action attribute

The title really says it all. I have made an attempt which failed with the error: Illegal attempt to pass arguments to a composite component lookup expression (i.e. cc.attrs.[identifier]). My attempt looks like this: <composite:interface> <composite:attribute name="removeFieldAction" method-signature="void action(java.lang.String)" /> </composite:interface> <composite:implementation> <h:commandButton value="Remove" action="#{cc.attrs.removeFieldAction('SomeString')}"/> </composite:implementation> What's the right way to do this? This is indeed not going to work. You cannot pass "extra"

When to use f:view and f:subview

阅读更多关于 When to use f:view and f:subview

I am not sure what are the benefits of using <f:view> and <f:subview> . I noticed that one could write JSF pages without using them. What are the benefits of using those tags? BalusC <f:view> The <f:view> is only useful if you want to explicitly specify/override any of the available attributes such as locale , encoding , contentType , etc or want to attach some phase listeners. E.g. <f:view locale="#{user.locale}" encoding="UTF-8" contentType="text/html"> If you don't specify it, then the sane JSF defaults will just be used instead, which is respectively UIViewRoot#getLocale() , UTF-8 and the

Include dynamic content containing JSF tags/components from stream

阅读更多关于 Include dynamic content containing JSF tags/components from stream

I am working on an application where I would like to include dynamic XHTML content from a stream. To handle this I wrote a taghandler extension which dumps the dynamic XHTML content to output component as UIOutput htmlChild = (UIOutput) ctx.getFacesContext().getApplication().createComponent(UIOutput.COMPONENT_TYPE); htmlChild.setValue(new String(outputStream.toByteArray(), "utf-8")); This works fine for XHTML content which has no JSF tags. If I have JSF tags in my dynamic XHTML content like <h:inputText value="#{bean.item}"/> , then they're printed as plain text. I want them to render as input

Passing the backing bean as a parameter to a Facelet include

阅读更多关于 Passing the backing bean as a parameter to a Facelet include

I have a Facelet that might be used in different applications. I don't to copy it, but reuse it. I need to pass the backing bean that will manage the view as a parameter, as some logic may vary according to the application where it is used in. I don't want to use a composite component, but just include the Facelet and specify which bean will manage the view. How can I achieve this? Let me give an example: <ui:composition template="/resources/common/templates/template.xhtml" xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:f="http://java.sun.com/jsf/core" xmlns

Why is the getter called so many times by the rendered attribute?

Related to a previous example, i tried to monitor my get/set methods on the server (when they are called, and how often). So, my actual been look such : @ManagedBean(name="selector") @RequestScoped public class Selector { @ManagedProperty(value="#{param.profilePage}") private String profilePage; public String getProfilePage() { if(profilePage==null || profilePage.trim().isEmpty()) { this.profilePage="main"; } System.out.println("GET "+profilePage); return profilePage; } public void setProfilePage(String profilePage) { this.profilePage=profilePage; System.out.println("SET "+profilePage); } }

JSF facelets template packaging

阅读更多关于 JSF facelets template packaging

As always, i'm a little confused. Here https://community.jboss.org/wiki/ModularWebAppsWithJSF2 i've learned that it is easy and works out of the box to bundle templates in separate jars since JSF 2.0. The only problem is: i can't get it working. I simply deploy a "page.xhtml" in all flavors (META-INF directory, resources directory, root; with and without faces-config.xml) in a jar that is included in the web application WEB-INF/lib and request something like http://host/demo/faces/page.xhtml or do an "include" or "decorate" on the template. I get an exception. Here Java EE6> Packaging JSF

I'd like to use non breaking spaces in my JSF page. I know, in plain HTML I could use for this and this works fine. However, when I put those in a Facelets page, then it errors as follows: Error Parsing /page.xhtml: Error Traced[line: 42] The entity "nbsp" was referenced, but not declared. How is this caused and how can I solve it? Facelets is a XML based view technology. XML has only five predefined entities . The is not among them. It works only when used in plain HTML or in legacy JSP (note: it doesn't work in JSPX as that's also XML based!). To fix this, you either need to declare
