JBoss Seam, Excel spreadsheet

#1

Estou tentando criar meu workbook com o Seam, estou tendo problemas qdo tento criar um spreadsheet baseado em um template. Sem template funciona normalmente.

Minha chamada:

[code] 

      		<s:button id="crep" 
      			action="#{reportsController.createProjectReport()}" 
      			value="Report"
      			propagation="join"
      			view="/secure/excel/projectReport.seam"
      			rendered="true" >
      			
      		</s:button>
    	</div>[/code]

Minha pagina construindo o workbook:

[code]<?xml version="1.0" encoding="ISO-8859-1" ?>

<e:workbook type=“jxl” templateURI="/secure/excel/projectsReport.xls">

<e:worksheet name="Projects" value="#{reportsController.reportList}" var="project" startColumn="0" startRow="1" selected="true">
  <e:column>
    <e:cell value="#{project.name}"/>
  </e:column>
</e:worksheet>

</e:workbook>

[/code]

E meu erro:

org.jboss.seam.excel.ExcelWorkbookException: Could not create workbook at org.jboss.seam.excel.jxl.JXLExcelWorkbook.createWorkbook(JXLExcelWorkbook.java:368) ... Caused by: java.lang.NullPointerException at jxl.read.biff.File.<init>(File.java:91) at jxl.Workbook.getWorkbook(Workbook.java:268) at jxl.Workbook.getWorkbook(Workbook.java:253) at org.jboss.seam.excel.jxl.JXLExcelWorkbook.createWorkbook(JXLExcelWorkbook.java:360)

Se eu removo o atributo templateURI meu spreadsheet eh gerado sem problemas.

Alguem jah fez isso antes, alguma ideia?!
