Seam 2.2.1 CR1 & Excel

[ginni]

I have searched the forums, followed all the examples and suggestions (including Lance's excellent post) but nothing will get me past this error:

Target Unreachable, 'excelExporter' returned null on 'org.jboss.seam.Namespace'

I modified my web.xml by adding

        <servlet>
                <servlet-name>Document Store Servlet</servlet-name>
                <servlet-class>org.jboss.seam.document.DocumentStoreServlet</servlet-class>
        </servlet>
        <servlet-mapping>
                <servlet-name>Document Store Servlet</servlet-name>
                <url-pattern>*.csv</url-pattern>
        </servlet-mapping>
        <servlet-mapping>
                <servlet-name>Document Store Servlet</servlet-name>
                <url-pattern>*.xls</url-pattern>
        </servlet-mapping>

I modified my components.xml by adding

under 'components'
        xmlns:excel="http://jboss.com/products/seam/excel"
        xmlns:document="http://jboss.com/products/seam/document"
under schema locations
        http://jboss.com/products/seam/document http://jboss.com/products/seam/document-2.2.xsd
        http://jboss.com/products/seam/excel http://jboss.com/products/seam/excel-2.2.xsd
and
<excel:document-store use-extensions="true"/>

I am using Maven2, added the dependency to the pom and ran mvn install, no errors

        <dependency>
                        <groupId>org.jboss.seam</groupId>
                        <artifactId>jboss-seam-excel</artifactId>
                        <version>2.2.1.CR1</version>
                        <scope>provided</scope>
                </dependency>

And in my page added

                <h:form id="excelReport">

                <rich:dataTable 
                        width="100%"
                        var="record"
                        id="authorizationListTable"
                        value="#{authorizationList}" 
                        ...
                ... columns...
                </rich:dataTable>
                <h:commandButton id="export" type="submit" value="Export to Excel" action="#{org.jboss.seam.excel.excelExporter.export('excelReport:authorizationListTable')}" />
                
                </h:form>

What could I possibly be missing?

Thanks,

More info. I searched for the class in Eclipse and noticed its packaging was different than how I had it, so I changed my button to this:

<h:commandButton id="exporter" type="Submit" value="Export to Excel" action="#{org.jboss.seam.excel.exporter.excelExporter.export('excelReport:authorizationListTable')}" />

and now I get this error:

Caused by: javax.faces.el.EvaluationException: org.jboss.seam.excel.ExcelWorkbookException: Could not find data table with id excelReport:authorizationListTable

So, I viewed the source of my page to make sure the rich datatable wasn't doing something strange, and I saw that my table's ID was indeed different.

<table class="rich-table table" id="authorizationListForm:excelReport:authorizationListTable" style="border-top-width: 1px;" border="0" cellpadding="0" cellspacing="0" width="100%">...

Then I modified my commandButton once again as is here:

<h:commandButton id="exporter" type="Submit" value="Export to Excel" action="#{org.jboss.seam.excel.exporter.excelExporter.export('authorizationListForm:excelReport:authorizationListTable')}" />

This works. I hope this helps someone else.
