Prezados,
Estou precisando criar um combobox no struts 2.
Eu fiz assim:
Minha classe action
public class ControleLogin extends ActionSupport implements SessionAware {
private List<String> cargo;
public String controla(){
cargo = new ArrayList<String>();
cargo.add("Vendedor");
cargo.add("Gerente");
cargo.add("Caixa");
return "sucess";
}
get's e set's...
JSP
<tr><td><s:combobox id="11" name="cargo" list="cargo" headerValue="-- Selecione o cargo --" headerKey="1" label="Cargo"></s:combobox></td></tr>
<tr>
Alguém poderia me explicar como fazer o combo e como recuperar seu valor escolhido pelo usuário?
Valeu!
Dá o erro:
SEVERE: Servlet.service() for servlet jsp threw exception
tag 'combobox', field 'list', id '11', name 'cargo': You must specify a collection/array/map/enumeration/iterator. Example: people or people.{name} - [unknown location]
