Jsf 数据表中的Primefaces子表不工作
我是jsf新手，在数据表中实现子表时遇到了一些问题。我的子表中的Der var atribute似乎没有对列表中的元素求值。另外，当我执行我的webapp并导航到xhtml站点时，也不会调用我的支持bean中的@PostConstruct方法。控制台中没有显示错误，所以我几乎不知道我做错了什么 支持BeanJsf 数据表中的Primefaces子表不工作,jsf,primefaces,datatable,Jsf,Primefaces,Datatable,我是jsf新手，在数据表中实现子表时遇到了一些问题。我的子表中的Der var atribute似乎没有对列表中的元素求值。另外，当我执行我的webapp并导航到xhtml站点时，也不会调用我的支持bean中的@PostConstruct方法。控制台中没有显示错误，所以我几乎不知道我做错了什么 支持Bean @Named(value = "selfEvalBean") @ViewScoped public class SelfEvaluationBean extends AbstractBean
