JSF: problema com validator

pimentaft · Novembro 19, 2008, 10:12am

Olá!
Estou com um problema ao validar 2 campos em uma pagina.
A validação é comparar se a hora inicial é menor que a hora final.Caso não seja, eu retorno uma mensagem na tela ao clicar no botao submit.Ele diz que o metodo não existe, mas o metodo jah esta criado no bean.

O erro é esse, que aparece no message do formulario:

/alocaturma.jsp(93,2) '#{bAloca.verificaHora}' Method not found: br.unig.scif.bean.AlocaBean@1055f4d.verificaHora(javax.faces.context.FacesContext, javax.faces.component.UIComponent, java.lang.Object)

meu jsp:

meu metodo no bean:

public void verificaHora(FacesContext context,UIComponent toValidate,ActionEvent event) {System.out.println("entrou");
		UIParameter parametroHoraInicio = (UIParameter) event.getComponent().findComponent("horainicio");
		String horaini = parametroHoraInicio.getValue().toString();
		UIParameter parametroMinutoInicio = (UIParameter) event.getComponent().findComponent("minutoinicio");
		String minutoini = parametroMinutoInicio.getValue().toString();
		horainicio = horaini + ":" + minutoini;
		
		UIParameter parametroHoraFim = (UIParameter) event.getComponent().findComponent("horafim");
		String horaf = parametroHoraFim.getValue().toString();
		UIParameter parametroMinutoFim = (UIParameter) event.getComponent().findComponent("minutofim");
		String minutof = parametroMinutoFim.getValue().toString();
		horafim = horaf + ":" + minutof;
		
		SimpleDateFormat formhora = new SimpleDateFormat("HHmmss");
		long min_1 = getMinutos(horainicio, formhora);   
	    long min_2 = getMinutos(horafim, formhora);   
		
		if (min_1 > min_2){
			((UIInput)toValidate).setValid(false);
		    FacesMessage message = new FacesMessage("Horário inválido");		    
		    context.addMessage(toValidate.getClientId(context), message); 
		}
	}

É a primeira vez que faço isso, se alguem puder me ajudar.

Grato!

Opa!
Vlw msm!
Agora se nao for mto abuso vc pode me ensinar como eu recupero os valores do formulário?

Queria fazer -te uma pregunta pimentaft,

Estou a tentar fazer umas validações tal como vc fez mas não estou a conseguir pois como coloco no cabeçalho do método:

depois como faço nessa linha:

uma vez que a class Object não tem o getComponent() e ele devolve erro.

Obrigado pela atenção
