Re: T5 Type to ValueEncoderFactory

[Nick Westgate]

Indeed. Hence the JIRA.

Howard has mentioned the possibility of merging the two type coercion systems.

Cheers,
Nick.

Thanks for the info. I'll add that to my component. However, it seems
odd that a simple conversion from Long to String isn't built in. It
seems to me that such standard conversions should be part of the
framework.

Tapestry just supports a ValueEncoder for String and Enum. If you want
additional
encoders you have to implement them yourself:

class LongValueEncoder implements ValueEncoder<Long>
{
        public String toClient(Long value)
        {
                return value == null ? "" : value.toString();
        }

        public Long toValue(String clientValue)
        {
                try
                {
                        return new Long(clientValue);
                }
                catch (NumberFormatException e)
                {
                        return null;
                }
        }
}

To use the encoder either add them to your AppModule:

    public static void contributeValueEncoderSource(
            MappedConfiguration<Class, ValueEncoderFactory> configuration)
    {
        configuration.add(Long.class, new
GenericValueEncoderFactory<Long>(new LongValueEncoder()));
    }

or add the encoder directly to your RadioGroup (or Select) components (see

http://tapestry.apache.org/tapestry5/tapestry-core/component-parameters.html)
