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:
...
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;
}
...
Thank you for your help!
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...

Answer 1

I don't know which PF version you are using, but the one that I use (2.2) has no attribute rowClasses.
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.
The error is of course a little generic and misleading. Seems like an unhandled exception from the lower xml parsing layers.
