Validation Error: Value is not valid
(3 answers)
Closed 8 years ago.
I keep getting this error addAddress:states: Validation Error: Value is not valid when using <p:selectOneMenu. I tried using the id and got rid of the converter, its doing the same. I tried debugging. Found that the converted is running twice and the last time it is checking blank value and returning null/false. What am I doing wrong? If need any more details let me know?
Code is as follows
Converter
#FacesConverter(value = "statemasterconverter", forClass = Statemaster.class)
public class StateConverter implements Converter {
public String getAsString(FacesContext context, UIComponent component,
Object value) {
return ConversionHelper.getAsString(value);
}
public Object getAsObject(FacesContext context, UIComponent component,
String value) {
return ConversionHelper.getAsObject(Statemaster.class, value);
}
}
Conversion Helper
public final class ConversionHelper {
private ConversionHelper() {
}
#SuppressWarnings("unchecked")
public static <T> T getAsObject(Class<T> returnType, String value) {
BigDecimal id = BigDecimal.ZERO;
if (returnType == null) {
throw new NullPointerException(
"Trying to getAsObject with a null return type.");
}
if (value == null) {
throw new NullPointerException(
"Trying to getAsObject with a null value.");
}
try {
id = BigDecimal.valueOf(Long.parseLong(value));
} catch (NumberFormatException nfe) {
return null;
}
Session session = HibernateUtil.getSessionFactory().openSession();
try {
T r = (T) session.load(returnType, id);
if (r != null)
Hibernate.initialize(r);
return r;
} catch (HibernateException e) {
e.printStackTrace();
} finally {
session.close();
}
return null;
}
public static String getAsString(Object value) {
if (value instanceof Gendermaster) {
Gendermaster result = (Gendermaster) value;
return String.valueOf(result.getGenderid());
} else if (value instanceof Salutationmaster) {
Salutationmaster result = (Salutationmaster) value;
return String.valueOf(result.getSalutationid());
} else if (value instanceof Countrymaster) {
Countrymaster result = (Countrymaster) value;
return String.valueOf(result.getCountryid());
} else if (value instanceof Statemaster) {
Statemaster result = (Statemaster) value;
return String.valueOf(result.getStateid());
}
return null;
}
}

<p:row>
<p:column>

<p:selectOneMenu id="country"

</p:column>

Answer 1

Use event="valueChange" in Ajax. and try to updated whole form by update="#form".
if above code is not work then try update=":id:id" update tag search id within the tag.
let consider this code.
<h:form id="myForm">
<h:sometag id="ineer1">
<p:ajax update="ineer3"/>// it is **not work**
<p:ajax update=":myForm:ineer2:ineer2"/>// it is **work**
</h:sometag>
<h:sometag id="ineer2">
<h:someoutfield id="ineer3"/>
</h:sometag>
<h:/form>
it is working at my end if not work then let me know.
Happy to help :)
