h:selectOneMenu s:selectItems sending selected bean value.

I have a dropdown list for UI:

CustodianAccountCreate.xhtml code:

<h:selectOneMenu value="#{custodianAccountHome.instance.bank}" style="width:110px" required="true" >
                        <s:selectItems value="#{allCustodians}" var="bankVar"  label="#{bankVar.name}" noSelectionLabel="Please Select.."/>
                    </h:selectOneMenu>

Here allCustodians is variable from seam context which is a list of bank object.

If you notice h:selectOneMenu has value custodianAccountHome.instance.bank where bank is an member of CustodianAccount class.

@Entity
public class CustodianAccount {

@ManyToOne
Bank bank;

}

My question is What is standard way to send the selected value to back end.
I get exceptions like "Value not valid" when I dont use s:convertEntity
or "Argument type mismatch" when I use s:convertEntity.

Do I have to use entityConverter.

I think, following should work if the custodianAccountHome.instance.bank is of compatible type with elements of allCustodians:

<h:selectOneMenu value="#{custodianAccountHome.instance.bank}" style="width:110px" required="true" > <s:selectItems value="#{allCustodians}" var="bankVar" label="#{bankVar.name}" noSelectionLabel="Please Select.."/> <s:convertEntity/> </h:selectOneMenu>

If it doesn't work, where is the Argument type mismatch thrown?
