I am populating the extendedDataTable using the data model shown below but when I select an entry, the backing bean method is being called but the selection variable is being set but with no keys, any help would be appreciated: // snippet from jsp              <r:simpleTogglePanel>                                        <f:facet name="header">                         <h:outputText value="User Search Results"/>                     </f:facet>                                         <a:outputPanel id="userSearchResultsPanel" >                         <r:extendedDataTable id="userTable"                                      height="200px"                                        value="#{userBean.dataModel}"                                        var="user"                                        selectionMode="single"                                        selection="#{userBean.searchSelection}">                                   <r:column sortOrder="ASCENDING"  >                                       <f:facet name="header">                                           <h:outputText value="User Name" />                                       </f:facet>                                       <h:outputText value="#{user.userName}" />                                   </r:column>                                   <r:column sortOrder="ASCENDING"   >                                       <f:facet name="header">                                           <h:outputText value="First Name" />                                       </f:facet>                                       <h:outputText value="#{user.firstName}" />                                   </r:column>                                   <r:column sortOrder="ASCENDING"  >                                       <f:facet name="header">                                           <h:outputText value="Surname" />                                       </f:facet>                                       <h:outputText value="#{user.surName}" />                                   </r:column>                                   <r:column sortOrder="ASCENDING">                                       <f:facet name="header">                                           <h:outputText value="Cost Center" />                                       </f:facet>                                       <h:outputText value="#{user.costCenter}" />                                   </r:column>                                                                     <a:support event="onselectionchange"                                              reRender="userDetailPanel"                                              action="#{userBean.identifySelectedUser}" />                           </r:extendedDataTable>                           <r:spacer height="10px" />                                                                    </a:outputPanel>                 </r:simpleTogglePanel> // Data Provider package util;
