哪里可能是问题？
xhtml页面（包含h：dataTable）修改后将dataTable和column标签替换为PrimeFaces，修改该类以返回List对象而不是DataModel ...
我看到了这个例子：
http://www.primefaces.org/showcase-labs/ui/datatableSorting.jsf
添加排序选项似乎很简单，因为我不能在java的类中添加任何特定的代码...
不过这是我的代码：
List.xhtml：
...
<p:dataTable value="#{progettiController.itemsList}" var="item" border="0" cellpadding="2" cellspacing="0" rowClasses="jsfcrud_odd_row,jsfcrud_even_row" rules="all" style="border:solid 1px" id="dataTable">
<p:column sortBy="#{item.id}">
<f:facet name="header">
<h:outputText value="#{bundle.ProgettiTitle_id}"/>
</f:facet>
<h:commandLink action="#{progettiController.prepareView}" value="#{item.id}"/>
</p:column>
<p:column sortBy="#{item.oggetto}">
<f:facet name="header">
<h:outputText value="#{bundle.ProgettiTitle_oggetto}"/>
</f:facet>
<h:outputText value="#{item.oggetto}"/>
</p:column>
...
ProgettiController.java：
...
private List itemsList;
...
public void setItemsList()
{
itemsList=logic.method.findProgettiByQuery(); //--- a method that returns a sublist of Progetti and that worked correctly
}
...
public List getProgetti()
{
return itemsList;
}
...
感谢您的帮助！
更新：好的，我想我明白问题出在哪里......它不在p：datatable而不在p：列中，但是我能够从网络中复制和粘贴..有时空格字符无法正确识别，所以我必须用新空格替换所有空格......
答案 0 :(得分：1)
我不知道您使用的是哪个PF版本，但我使用的版本（2.2）没有属性rowClasses。
但是，h:dataTable具有此属性。但我不知道Primefaces如何处理这种情况。根据我的经验，有时它可以使用底层jsf组件的属性，有时不会。
错误当然有点普遍和误导。看起来像是来自较低xml解析层的未处理异常。
