Hi
I am using Richfaces richfaces-ui-3.3.3.Final with jojarra-2.0.3 Core JSF and Jave 1.6 running in tomcat 6.0.29.
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>
