Hi John,
The problem is that on <f:selectItem /> the attribute itemValue has to be of
the same type as the property in the managed bean. In your case this is
ClientIdType.
However you are providing the String "CardNumber" as the value which is
definitely not the same as the enum value ClientIdType.CardNumber. Thus you
get the Exception.
Try using the following:
<f:selectItem itemValue="#{bean.propertyThatResolvesToCardNumber}"
itemLabel="#{msgs['labelCardNumber.full']}:" />
with Bean.getPropertyThatResolvesToCardNumber() returning the enum value
ClientIdType.CardNumber.
Regards,
Jakob
