UISelectOne: Value is not a valid option.

[blady]

Hi!

I have a big problem with JSF validation. I don't know why but when i submit a form i get "Value is not a valid option" error for h:selectOneMenu control. I'm using @SelectItems binder with my converter:

xhtml:

<h:selectOneMenu class="configInput"
 id="tAccountStatus"
 value="#{bankAccountControl.instance.idBankAccountStatus}"
 converter="#{bankAccountStatusFinder.converter}">
 <f:selectItems value="#{bankAccountStatusList}"/>
</h:selectOneMenu>

#{bankAccountStatusList}:

@SelectItems(valueStrategy=SelectItems.Strategy.OBJECT, labelMethod="getStatusName")
 private List<BankAccountStatus> bankAccountStatusList;

@Factory("bankAccountStatusList")
public void findBankAccountStatuses() {
 bankAccountStatusList = entityManager
 .createQuery("FROM BankAccountStatus bas ORDER BY bas.statusName")
 .getResultList();
}

#{bankAccountControl.instance}:

@Valid
private BankAccount bankAccount;

public BankAccount getInstance() {
 return bankAccount;
}

#{bankAccountStatusFinder.converter}:

static public class BankAccountStatusConverter
 implements Converter, Serializable {

 private static final long serialVersionUID = 3820066884549543875L;

 List<BankAccountStatus> bankAccountStatusList;

 public BankAccountStatusConverter(
 List<BankAccountStatus> bankAccountStatusList){
 this.bankAccountStatusList = bankAccountStatusList;
 }

 public String getAsString(FacesContext facesContext,
 UIComponent component,
 Object obj) {
 if (obj == null) return null;

 BankAccountStatus bankAccountStatus = (BankAccountStatus) obj;
 String val = String.valueOf(bankAccountStatus.getIdBankAccountStatus());
 return val;
 }

 public Object getAsObject(FacesContext facesContext,
 UIComponent component,
 String str) throws ConverterException {

 if (str == null || str.length()==0) {
 return null;
 }

 long id = Long.valueOf(str).longValue();
 for (BankAccountStatus bankAccountStatus : bankAccountStatusList){
 if (bankAccountStatus.getIdBankAccountStatus() == id) {
 return bankAccountStatus;
 }
 }
 return null;
 }
}

There is no any exception on console, anything. Only message from JSF that "Value is not a valid option", i don't know how to make it works.

Please help.

That error message normally occurs when the submitted value is not one of the possible values (i.e. the submitted value is not an item in #{bankAccountStatusList}). What scope is #{bankAccountStatusList} outjected into (is a long-running conversation in process)?

A way to fix is to override equals in BankAccountStatus to compare on id equality rather than object instance equality.
