Jsf ui:repeat size doesn't gets java bean value

由 核能气质少年 提交于 2019-12-11 10:42:03
问题 JSF 2.0's ui:repeat tag gets the value of java bean(arraylist) as it's value property but size property doesn't. I am using the ui repeat inside of a datatable which shows statuses iteratively and ui repeat shows comments for each status. I am giving the size property of ui repeat from a java class because each status has a different number of comments. Therefore size should be decided dynamically. Here is the summary of what i've done. Model classes: @ManagedBean @RequestScoped public class

问题 Is there any way using EL to retrieve a children list so i can iterate through it with <ul> <ui:repeat value="#{Magic El expression}" var="children" > <li> <p> #{children.title} *</p> </li> </ui:repeat> </ul> <div> <cc:insertChildren /> </div> * perhaps #{children.attrs.title} I don't know?

问题 we are going to migrate our JSF 1.2 project to JSF 2. We are already using facelets (not JSPs) as our presentation technology. We are using lot of JSTL -> "xmlns:c="http://java.sun.com/jstl/core" We are using lot of <c:if> statements. I know that JSF2 brings rendered attribute, which should also evaluate boolean expressions. Should I bother rewriting stuff to new rendered attribute or is it ok to continue using JSTL in JSF2? 回答1: JSTL works the same way in JSF2 as it worked in JSF1. The
