Dear Team,

Towards http://seamframework.org/Community/RichdatatableToExcelExportIsEasyButIGetError#comment49459 tried to export the rich:dataTable contents.

However, on button-action it throws:

Caused by: javax.el.PropertyNotFoundException: /TimesheetsList.xhtml @216,79 action="#{excelExporter.export('timesheetsListForm:timesheetsList')}": Target Unreachable, identifier 'excelExporter' resolved to null

Here are the steps followed and errors ocured:
1. web.xml: modifed as per above post
2. component.xml: problem to add <excel:document-store use-extensions="true"/> OR <document:document-store use-extensions="true"/> [Deployment failed] So only added name space
3. jboss-web.xml:
    <class-loading java2ClassLoadingCompliance="false">
        <loader-repository>
            seam.jboss.org:loader=Portal
            <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
            seam.jboss.org:loader=seam-excel
            <loader-repository-config>java2ParentDelegation=false</loader-repository-config>
        </loader-repository>
    </class-loading>
4. xyz.xhtml:
<a:form id="timesheetsListForm">
<rich:dataTable id="timesheetsList"
.
.
.

          <h:commandButton id="export_top" type="submit"
                               styleClass="submit_button" 
                               value="Export to Excel"      
                               action="#{ExcelExporter.export('timesheetsListForm:timesheetsList')}"/>
          </a:form>


Used:
JBOSS server 4.2.1 GA
Seam 2.0.1
Seam-excel.2.1.0GA [as other jar lik was not available]
richfaces3.3.1

Please assist as what am I missing?
