richFaces — GUJ

tenho uma tabela e gostaria de pegar a linha selecionada e nao sei como faço…

estou usando o richFaces e <rich:extendedDataTable value="#{cooperadoHandler.listaCooperados}">

creio q o erro e devido ao tipo da var listaCooperados… mais nao sei q tipo fazer… na tabela mostra o nome e o cpf do objeto cooperado.

procurei na pagina http://livedemo.exadel.com/richfaces-demo/richfaces/extendedDataTable.jsf?tab=info&cid=249974 e nao encontrei o codigo da classe java
so o codigo do jsp!!!

1. javax.servlet.ServletException: /jsp/cadastros/cadCooperado.jsp(305,1) '#{cooperadoHandler.linhaSelecionada}' Cannot convert [] of type class java.util.ArrayList to interface org.richfaces.model.selection.Selection  
   2.     javax.faces.webapp.FacesServlet.service(FacesServlet.java:277)  
   3.     org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:178)  
   4.     org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:290)  
   5.     org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:388)  
   6.     org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:515)

Obrigado ae galera… e desculpa qlqr coisa!

Bom isso conseguir resolver to com outro problema ... rsrsrs

link bom pra ajudar http://lists.jboss.org/pipermail/richfaces-svn-commits/2008-December/011900.html bom a solução do primeiro problema eh

O novo problema eh q nao consigo, apos o click na linha da tabela atualizar um campo pode ser ou
o importante e q funcione..

estou usando o Ajax pra fazer mais nao to conseguindo
pq nao consigo botar um metodo no parametro "action" e no site de referencia a cima ta
um metodo normal void... agora chama o meu metodo nao sei pq.
