问题描述
- PrimeFaces 5.1
- Mojarra 2.2.2
- 春季4.0.2
我有以下XHTML页面:
I have the following XHTML page:
<ui:composition xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core"
xmlns:p="http://primefaces.org/ui"
xmlns:c="http://java.sun.com/jsp/jstl/core"
template="/WEB-INF/pages/main/admin.xhtml">
<ui:define name="contentBody">
<p:dataTable widgetVar="weekdayTable"
value="#{weekdayList.countries}"
var="ctr"
styleClass="weekdaysManagementDatatable">
<p:column width="100"
sortBy="#{ctr.desc}"
headerText="#{msg['page.admin.weekday.list.country']}">
<h:outputText value="#{ctr.desc}" />
</p:column>
<c:forEach items="#{weekdayList.weekdays}" var="day">
<c:set var="open" value="#{weekdayList.checkOpen(ctr.id, day.date)}"/>
<p:column width="20" headerText="#{utils.dateToDayWeek(day.date)}">
<h:selectBooleanCheckbox value="#{open}">
<p:ajax listener="#{weekdayList.handleDay(ctr.id, day.id)}" />
</h:selectBooleanCheckbox>
</p:column>
</c:forEach>
</p:dataTable>
</ui:define>
</ui:composition>
关联的bean如下:
@Named("weekdayList")
@Scope("session")
public class AdminWeekdayListController implements Serializable {
...
public boolean checkOpen(String ctrId, Date date) {
Country ctr = countryDao.getById(ctrId);
List<WeekDay> list = weekdaysMap.get(ctr);
if (list == null) {
return true;
}
WeekDay day = new WeekDay();
day.setDate(date);
for (WeekDay wd : list) {
if (wd.compareTo(day) == 0) {
return wd.isOpen();
}
}
return true;
}
}
我还有另一个bean，用于维护要显示的当前页面，整个应用程序都是使用AJAX编写的.用户始终位于同一页面上，并且内容是动态加载的.
I have another bean which maintains the current page to display and the whole the application is made with AJAX. The user is always on the same page and the content is dynamically loaded.
当我重新加载(F5)页面时，所有内容似乎都能正常工作.
但是，如果我进行常规导航(加载AJAX)，则会得到PropertyNotFoundException ...
When I reload (F5) the page, all seems to work correctly.
But, if I go trought the normal navigation (AJAX loading), I have got a PropertyNotFoundException...

但是让我认为问题不在于我的bean的原因是，如果我从<h:selectBooleanCheckbox/>的值中删除了#{open}，它就可以正常工作(除了未按照我想要的方式检查复选框) :
But what make me think that the problem does not come from my bean is, if I remove the #{open} from the value of the <h:selectBooleanCheckbox/> it perfectly works (except that the checkboxes are not checked the way I want):
<c:forEach items="#{weekdayList.weekdays}" var="day">
<c:set var="open" value="#{weekdayList.checkOpen(ctr.id, day.date)}"/>
<p:column width="20" headerText="#{utils.dateToDayWeek(day.date)}">
#{open}
<h:selectBooleanCheckbox value="true">
<p:ajax listener="#{weekdayList.handleDay(ctr.id, day.id)}" />
</h:selectBooleanCheckbox>
</p:column>
</c:forEach>
如您所见，我一直在使用#{open}而不是在value礼盒内使用.
As you can see I keep using #{open} but not inside the value attibute.
我错了什么?我想念什么吗?有错误吗?
What did I wrong? Am I missing something? Is there a bug?
谢谢.
推荐答案
所以...我找到了解决方案"，并回答了自己的问题.
So... I have found a "solution", and respond to my own question.
我为checkOpen方法添加了伪造的getter和setter方法.因此，bean看起来像这样:
I added fakes getter and setter for the method checkOpen. So the bean looks like this:
@Named("weekdayList")
@Scope("session")
public class AdminWeekdayListController implements Serializable {
...
public boolean getCheckOpen() {
return true;
}
public void setCheckOpen(boolean b) {
}
public boolean checkOpen(String ctrId, Date date) {
Country ctr = countryDao.getById(ctrId);
List<WeekDay> list = weekdaysMap.get(ctr);
if (list == null) {
return true;
}
WeekDay day = new WeekDay();
day.setDate(date);
for (WeekDay wd : list) {
if (wd.compareTo(day) == 0) {
return wd.isOpen();
}
}
return true;
}
}
通过这种方式，JSF认为checkOpen是有效的(读/写)属性， BUT 调用checkOpen(String ctrId, Date date).它从不调用getter或setter ...
This way JSF thinks checkOpen is a valid (read/write) attribute, BUT calls checkOpen(String ctrId, Date date). It never calls the getter or the setter...
如果有人可以解释这一点，我将不胜感激.如果有人有更好的解决方案，那我在听.
If someone can explain this, I will be gratefull. And if someone has a better solution, I am listening.
