Re: select component

Tony,

Sorry I didn't reply to this earlier. I'm sure you figured it out by
now, but for the record the canonical answer comes from Tapestry's own
TapestryModule class
(http://svn.apache.org/viewvc/tapestry/tapestry5/trunk/tapestry-core/src/main/java/org/apache/tapestry5/services/TapestryModule.java?view=markup),
which is equivalent to your code:

    @SuppressWarnings("all")
    public static void
contributeValueEncoderSource(MappedConfiguration<Class, Object>
configuration)
    {
        configuration.addInstance(Object.class,
TypeCoercedValueEncoderFactory.class);
        configuration.add(String.class, new StringValueEncoder());
        configuration.add(Enum.class, new EnumValueEncoderFactory());
    }
