jsf-2

问题 Is it possible to invoke more than one listener method using a single command component? For example, A view scoped bean: @ManagedBean @ViewScoped public final class ViewScopedBean implements Serializable { @ManagedProperty(value = "#{sessionScopedBean}") private SessionScopedBean sessionScopedBean; //Getter/Setter. private static final long serialVersionUID = 1L; public ViewScopedBean() {} public void action() { //Do something. sessionScopedBean.action(); } } A session scoped bean:

问题 I'm using JSF2 on GlassFish 3. I have a form that accepts and optional phone number. I have this custom phone number validator (below), and I have the field set to required="false" because the phone number is optional in the form. The problem is, the value in the field is always getting validated. Shouldn't the validation be skipped when there is no value specified? There must be something I'm doing wrong. Any help is appreciated, thanks! <h:outputText value="#{msg.profile_otherPhone1Label}#

问题 This question already has answers here : Performing user authentication in Java EE / JSF using j_security_check (4 answers) Closed 3 years ago . I am trying - with JSF 2.0 - to implement in a neat way the login/remember me/logout management. Since the traditional <form action="j_security_check" ... way lacks of flexibility I decided to follow a different path, but I found a problem. Declarative security is properly set both in the application server through <security-domain> and in web.xml

问题 I am learning/using JSF 2.0 (Sun Mojarra) now and I want to have a tabbed pane in my webapp (single tabs could named be General, Detail1,Detail2,...). How do I achieve this? I haven't found any documetation for this so far :( 回答1: Others have already hinted it: Mojarra is a basic JSF implementation. It offers the minimum set of mandatory components to cover the most of existing HTML elements (forms, input fields and tables). Since HTML does not offer a tabbed panel in a single element, the

问题 My question is related to this one Get all hidden input fields in JSF dynamically but it's not the same as I want to work with JSF and not plain HTML, and assuming that I have the following in my .xhtml file: <h:inputHidden id="name1" value="SomeValue1"/> <h:inputHidden id="name2" value="SomeValue2"/> I developed a small code where I tried to get all the h:inputHidden tags dynamically and print their values to the console, but the problem is that I can't figure out a way how to make

问题 I have an issue with the order and number of executions of an f:event type="preRenderView" . During my search here I found as usual answers from BalusC in this and this post related to my problem - still it leaves two questions for me: When I put one f:event type="preRenderView" in the template file (for managing common tasks like checks about the user state which applies for all my views) and another f:event type="preRenderView" in each view (for handling view specific initializations), I
