A problem about Passing data in EVENT scope with Seam excel

[brin]

Recently,I encountered a problem about passing data in EVENT scope with Seam excel.
the exception is :A worksheet's value must be an Iterable, DataModel or Query.


I have been tested successful when I changed the scope of the component  "paySuccessAction" to SESSION ; but it won't work in scope which below the seesion scope.

the question is :How can I pass the data in Event Scope?

1.the component file PaySuccessAction.java :
`
@Name("paySuccessAction")
@Scope(ScopeType.PAGE)
public class PaySuccessAction
{
       @Out(required=false,scope=ScopeType.EVENT)
       private List<TPaymentRecord> records;
       
       public void getBatchList()
       {
            records=paymentRecordBO.getInstancyList();
       }

       public List<TPaymentRecord> getRecords() {
           return records;
       }


}

`

2.the config file paySuccess.page.xml :
`
<?xml version="1.0" encoding="UTF-8"?>
<page view-id="/module/payment/record/paymentSuccess.xhtml" xmlns="http://jboss.com/products/seam/pages"
      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:schemaLocation="http://jboss.com/products/seam/pages http://jboss.com/products/seam/pages-2.2.xsd">
      <navigation from-action="#{paySuccessAction.getBatchList()}">
       <render view-id="/module/payment/record/batchExcelExport.xhtml"/>
      </navigation>
</page>

`

3.the excel templete batchExcelExport.xhtml :
`
<e:workbook filename="batchExcelExport.xls"
xmlns:e="http://jboss.com/products/seam/excel"
xmlns:f="http://java.sun.com/jsf/core">
<e:worksheet  startRow="2" value="#{records}" var="record">
.....
</e:worksheet>
</e:workbook>
