由 拜拜、爱过 提交于 2021-02-19 07:52:29
问题 Lets assume I want to access the value of a sibling component in an ActionListener. The following fragment is not working as expected, resulting in a ClassCastException: java.util.HashSet cannot be cast to java.lang.String public void processAction(final ActionEvent event) { FacesContext ctx = FacesContext.getCurrentInstance(); UIComponent sibling = event.getComponent().findComponent("inputText"); String value = (String) sibling.getValue(); ... } If I change the essential part to the

问题 What would the method facesContext.isValidationFailed() return after the Render Response Phase when the validation fails? It returns false for me in this case. 回答1: It will only return true when FacesContext#validationFailed() has been called by the JSF validation internals or by your own code as follows: FacesContext.getCurrentInstance().validationFailed(); As far JSF internal code is concerned, only UIInput#processValidators() and UIViewParameter#processValidators() will implicitly call

How to change locale in JSF 2.0?

由 半世苍凉 提交于 2021-02-15 11:46:08
问题 In my app, user should be able to switch the locale (the language used to render text on pages). Tons of tutorials are using FacesContext.getCurrentInstance().getViewRoot().setLocale(). For example: http://www.mkyong.com/jsf2/jsf-2-internationalization-example/. But, that simply doesn't work in JSF 2.0 (it did work in 1.2). The language never switches. No errors or anything. The same code worked fine in JSF 1.2. What is the correct and definitive approach? I have cobbled together a solution,

问题 I am using Spring for my DI. Is there an equivalent of @ManagedProperty? I want to inject the value from one view scoped bean into another one on the next page. e.g @Component @Scope("view") public class Page1Bean(){ private String value; } @Component @Scope("view") public class Page2Bean(){ @ManagedProperty(value = #{page1Bean}") //doesnt work in Spring private Page1Bean bean; } 回答1: @Resource or @Autowired should work. @Resource is the Java EE implementation, @Autowired is the spring
