Using matrix of Doubles as data source for rich:dataTable

[lenyas66]

I am trying to use Vector<Vector> as the source of data for rich:dataTable and getting the following error:

17:28:13,218 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/NBP].[Faces Servlet]] Servlet.service() for servlet Faces Servlet threw exception
com.sun.facelets.FaceletException: Error Parsing /piQueryTool.xhtml: Error Traced[line: 143] The value of attribute "value" associated with an element type "h:outputText" must not contain the '<' character.

Could somebody advise how I could do it?

Please see the code snippet below:

<div id="tableDiv" style="visibility:visible">
 <h:panelGrid columns="2">
 <rich:dataTable id="returnedData" value="#{piQueryToolBean.retData}" var="dataItems" >
 <f:facet name="header"><h:outputText value="Performance Statistics" /></f:facet>
 <rich:columns value="#{piQueryToolBean.statistics}" var="columns" index="ind" >
 <f:facet name="header">
 <h:outputText value="#{columns.displayName} />
 </f:facet>
 <h:outputText value="#{dataItems[index]}" />
 </rich:columns>
 </rich:dataTable>
 </h:panelGrid>
 </div>

Java code declaration:

private Vector<Vector> retData;

Would appreciate any advice.

Thanks,

Leonid

The error was coming from missing quote in outputText definition below:

<h:outputText value="#{columns.displayName}" />

Still, I can't see it processing the values contained in retData.

It throws an exception instead:

18:40:34,178 ERROR [org.richfaces.taglib.ColumnsHandler] FOREACH_BAD_ITEMS
javax.servlet.jsp.JspTagException: FOREACH_BAD_ITEMS

One more correction:

The declaration in Java is obviously

private Vector<Vector<Double>> retData;

Jsf has no standard DataModel instance for Vector's data. Use java.util.List instead or create your own DataModel that works with vectors.
