myfaces datatable

[James Clinton]

Can some please help me getting the datatable to work. currentl jsf fails because:

Facet Tag can only have one child UIComponent

<f:facet name="header">                
 <t:commandSortHeader columnName="type" arrow="false">
  <h:outputText value="COLUMN 1" />    
 </t:commandSortHeader>
</f:facet>

However all the examples I have seen allow this

[Ali Gohar]

what error do you get? Post the complete code may be problem is in some other part of the code

[James Clinton]

As requested:

<h:dataTable 
 id="items" 
 value="${riskLimits}" 
 var="risk" 
 rowClasses="oddRow, evenRow" 
 headerClass="tableHeader"
 sortable="true"
 sortColumn="#{riskTest.sort}"
 sortAscending="#{riskTest.ascending}">
             
 <f:facet name="header">
  <h:outputText value="RISK TABLE HEADER"  />
 </f:facet>
 
  <h:column>           
   <f:facet name="header">                    
     <t:commandSortHeader columnName="type" arrow="false">
       <h:outputText value="COLUMN 1" />    
     </t:commandSortHeader>
   </f:facet>
 <h:outputText value="#{risk.str1}" />
 </h:column>
</h:dataTable>

Hi James,

<t:commandSortHeader> tag can only be nested inside an extended datatable ie. <t:dataTable>. so use <t:dataTable> in your code instead of <h:dataTable>

Hope it resolves the issue

[James Clinton]

sadly, this still throws up the same error.

James,

Are you using facelets? I had the same problem until I got Tomahawk 1.1.5 SNAPSHOT and followed the directions in FaceletsReadMe.txt.

This was due to a class loading issue.
