Recarregar página depois de um download - JSF/Primefaces [RESOLVIDO]

Preciso de uma solução onde depois do download de um arquivo a página seja recarregada.

Quanto tento fazer isso num "action" depois do download recebo:

Exception when handling error trying to reset the response.: java.lang.IllegalStateException

Estou baixando assim:

private void baixarArquivo(byte[] bytes, String nomeAquivo) throws IOException {

		FacesContext facesContext = FacesContext.getCurrentInstance();

		HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
		ServletOutputStream servletOutputStream = response.getOutputStream();

		response.setContentType("application/pdf");
		response.setHeader("Content-Disposition", "attachment;filename=\"" + nomeAquivo + "\"");

		servletOutputStream.write(bytes);
		servletOutputStream.flush();
		servletOutputStream.close();
		facesContext.responseComplete();
	}

Alguém tem alguma ideia?

Pro meu caso resolveu diretinho como segue:

protected void gerarArquivo(byte[] bytes, String nomeAquivo) throws IOException {
		FacesContext facesContext = FacesContext.getCurrentInstance();
		HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext().getResponse();
		ServletOutputStream servletOutputStream = response.getOutputStream();

		response.setContentType("application/pdf");
		response.setHeader("Content-Disposition", "attachment;filename=\"" + nomeAquivo + "\"");
		response.setHeader("Refresh", "3; url = \"listagens.jsf\""); // AQUI

		servletOutputStream.write(bytes);
		servletOutputStream.flush();
		servletOutputStream.close();
		facesContext.responseComplete();
	}
