Problema h:selectOneMenu

Front-end
#1

Boa tarde

Estou tentando usar h:selectOneMenu com um objeto como retorno, porém ele sempre retorna null, segue:

<h:selectOneMenu id="#{msgs.id_type}" style="width: 140px;" value="#{identificationBean.selectedDataType}" required="true" converter="#{dataTypeConverter}"> <f:selectItem itemLabel="#{msgs.id_chooseOne}" itemValue="" noSelectionOption="true"/> <f:selectItems value="#{identificationBean.dataTypes}" var="data" itemLabel="#{data.name}" itemValue="#{data}"/> </h:selectOneMenu>
BackBean[code]private DataType selectedDataType;
private List dataTypes = new ArrayList();
…

public List getDataTypes() {
if(dataTypes.size() == 0) {
try {
dataTypes = identificationService.getDataTypesForIdentifications();
} catch (DEException e) {
e.printStackTrace();
}
}
return dataTypes;
}

Get e set…[/code]
Meu converter:[code]@Component(value=“dataTypeConverter”)
public class DataTypeConverter implements Converter{

@Autowired
private IdentificationService identificationService;

@Override
public Object getAsObject(FacesContext context, UIComponent component, String value) {
	if(value != null){
		try {
            List<DataType> list = identificationService.getDataTypesForIdentifications();
            for(DataType dataType : list){
            	if(dataType.getName().equals(value))
            		return dataType;
            }
        } catch (DEException e) {
            e.printStackTrace();
        }
	}		
    return null;
}

@Override
public String getAsString(FacesContext context, UIComponent component, Object value) {
	if(value != null && value instanceof DataType) {  
		return ((DataType)value).getName();
	}
	return null;
}

}[/code]
