问题 I am looking for a way to change the update attribute of a primefaces command button from the backing bean after the form submit. What i am trying to achieve is to update the component id's based on the results from backing bean method.

问题 I have a @ViewScoped bean with a List<String> containing plain HTML. I want to iterate over this list and output plain html: <c:forEach items="#{bean.list}" var="html"> <f:verbatim>#{html}</f:verbatim> </c:forEach> That snippet above works well but when the page is refreshed the bean costrunctor is recalled.
