I'm doing a Java web application and I ran into a problem with the converter to be used in selectmanycheckbox . The converter I made was this:
@FacesConverter(forClass = Indicacao.class)
public class IndicacaoConverter implements Converter {
// @Inject
private Procedimentos procedimentos;
public IndicacaoConverter() {
procedimentos = CDIServiceLocator.getBean(Procedimentos.class);
}
@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
Indicacao retorno = null;
if (value != null) {
Long id = new Long(value);
retorno = procedimentos.porId(id);
}
return retorno;
}
@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
if (value != null) {
Indicacao indicacao = (Indicacao) value;
return indicacao.getId() == null ? null : indicacao.getId().toString();
}
return "";
}
}
The error ....
