问题可能出在哪里?
已修改xhtml页面(包含h:dataTable)，并用PrimeFaces替换了dataTable和column标记，对该类进行了修改以返回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，因为我一定不能在Java类中添加任何特定的代码...
但是这是我的代码:
List.xhtml:

Where could be the problem?
The xhtml page (that contained a h:dataTable) was modify replacing the dataTable and the column tag with those of PrimeFaces, the class was modify to return a List object and not a DataModel...
I saw this example:
http://www.primefaces.org/showcase-labs/ui/datatableSorting.jsf
and it seems simple to add the sorting option because I must not add any specific code into java's class...
However here it is my code:
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:

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;
    }
    ...

谢谢您的帮助！

更新:好的，我想我知道问题出在哪里……它不在p:datatable和p:column中，而是在我从网络中复制和粘贴的能力.有时无法正确识别空格字符，因此我必须将所有空格替换为新的空格...

Update: Ok, I think I understand where the problem was... It's not in p:datatable and not in p:column but in my ability to copy and paste from the web... Sometimes the space character isn't recognized correctly so I must replace all spaces with new spaces...

推荐答案

我不知道您使用的是哪个PF版本，但是我使用的那个(2.2)版本没有属性rowClasses.

I don't know which PF version you are using, but the one that I use (2.2) has no attribute rowClasses.

但是，h:dataTable具有此属性.但是我不知道Primefaces如何处理这种情况.根据我的经验，有时可以使用底层jsf组件的属性，有时不能.

However, h:dataTable has this attribute. But I don't know how Primefaces handles this situation. From my experience, sometimes it works to use attributes of underlying jsf components, sometimes not.

该错误当然有点笼统和误导.似乎是来自较低的xml解析层的未处理异常.

The error is of course a little generic and misleading. Seems like an unhandled exception from the lower xml parsing layers.
