@PreDestroy never called on @ViewScoped

由 只愿长相守 提交于 2019-12-17 10:50:11
问题 I have a @ViewScoped bean that has a method with an @PreDestroy annotation that should make sure some remote connections are closed. However, the method is not called when the user navigates away. Is there anything one can do wrong? Do I have to register anything anywhere in order to make it work? It's a simple public method ( void ) that throws no exception. I'm using JSF 2 (MyFaces) with Tomcat 7.0.12. Could it be a problem with Tomcat? UPDATE The @PostConstruct annotation works fine. 回答1:

How to set maxlength attribute on h:inputTextarea

由 点点圈 提交于 2019-12-17 09:42:19
问题 How can I limit the length of <h:inputTextarea> ? For <h:inputText> it works fine with maxlength attribute. However, this attribute is unavailable in <h:inputTextarea> . 回答1: HTML5 + JSF 2.2+ If you're using HTML5 and JSF 2.2+, specify it as a passthrough attribute. <html ... xmlns:a="http://xmlns.jcp.org/jsf/passthrough"> <h:inputTextarea value="#{bean.text}" a:maxlength="2000" /> HTML5 + JSF 2.0/2.1 If you're using HTML5, but not JSF 2.2 yet, use OmniFaces Html5RenderKit to recognize new

Is it possible to disable f:event type=“preRenderView” listener on postback?

由 别来无恙 提交于 2019-12-17 07:26:46
问题 Is it possible to "disable" triggering of this action when doing postback? <f:metadata> <f:event listener="#{defaultNewQuestionHandler.init}" type="preRenderView" /> </f:metadata> 回答1: That's not possible with <f:event> . You need to manually check FacesContext#isPostback() inside the listener method. public void init() { if (!FacesContext.getCurrentInstance().isPostback()) { // ... } } In the upcoming JSF 2.2 <f:viewAction> tag, which is supposed to replace this <f:event type="preRenderView"

what to use, managed beans (backing beans) or entity beans?

由 本小妞迷上赌 提交于 2019-12-17 07:25:32
问题 I see a lot of examples marking beans as entity beans (@Entity) & named beans (CDI), so as to avoid creating 2 classes (managed bean & entity bean) and also to make use of Bean Validation so that validation can be performed on both client & server. So should I be using a single class or not, are there any issues or should I be having my managed beans or service layer create entity beans using the data from managed beans ? 回答1: The @Named or @ManagedBean annotations are typically used to let
