Relatório JSF Ireport - Error retrieving field value from bean: nome

@JosueSantos escreveu:

Alguém pode me ajudar? Relatório em Java é um saco! Não estou conseguindo acessar a chave estrangeira para colocar o nome da cidade no Relatório de Instituição.

Classe Intituicao:
@ManyToOne
@JoinColumn(name="cidade", nullable = false)
private Cidade cidade= new Cidade();

Classe Cidade:
//Chave estrangeira composição
@ManyToOne
@JoinColumn(name="estado", nullable = false)
private Estado estado = new Estado();

Chamando o metodo gerar relatório no xhtml Intituição:
h:commandButton value="Exportar PDF" actionListener="#{instituicaoBean.exportarPDF}"

METODO:
public void exportarPDF(ActionEvent actionEvent, Instituicao instituicao, Cidade cidade) throws JRException, IOException{
InstituicaoDAO instituicaoDAO = new InstituicaoDAO();
instituicaos = instituicaoDAO.listar();

	File jasper = new File(FacesContext.getCurrentInstance().getExternalContext().getRealPath("/reports/instituicao.jasper"));

	Map<String, Object> parametros = new HashMap<String, Object>();

	parametros.put("instituicao", instituicao.getRazaosocial());
	parametros.put("instituicao", instituicao.getCnpj());
	parametros.put("instituicao", instituicao.getDataCadastro());
	parametros.put("instituicao", instituicao.getEndereco());
	parametros.put("instituicao", instituicao.getComplemento());
	parametros.put("instituicao", instituicao.getTelefone());
	parametros.put("instituicao", instituicao.getFundador());
	parametros.put("instituicao", instituicao.getCep());
	parametros.put("instituicao", instituicao.getEmail());
	parametros.put("instituicao", instituicao.getSite());
	parametros.put("cidade", instituicao.getCidade().getNome());

	JasperPrint jasperPrint = JasperFillManager.fillReport(jasper.getPath(), parametros, new JRBeanCollectionDataSource(this.instituicaos));

	HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
	response.addHeader("Content-disposition","attachment; filename=Instituicao.pdf");
	ServletOutputStream stream = response.getOutputStream();

	JasperExportManager.exportReportToPdfStream(jasperPrint, stream);
	stream.flush();
	stream.close();

	FacesContext.getCurrentInstance().responseComplete();			
}

Compilo JRXML e não apresenta erro, porem na hora de rodar a aplicação da o erro:
