Example: A Spinner Component

Example: An application with two spinners.

• These spinners are slow because they cause round trips to the server—fixed later
• Both insist on integer values—bad data entered directly handled by standard integer converters
• Integer ranges not enforced because they need custom validators—fixed later
• Here is how they are used:

     <%@ taglib uri="http://corejsf.com/spinner" prefix="corejsf" %>
     ...
     <corejsf:spinner value="#{cardExpirationDate.month}"
         id="monthSpinner" minimum="1" maximum="12" size="3"/>
     <h:message for="monthSpinner"/>
     ...
     <corejsf:spinner value="#{cardExpirationDate.year}"
         id="yearSpinner" minimum="1900" maximum="2100" size="5"/>
     <h:message for="yearSpinner"/>
