[T5] Configurable value encoders for select?

[Dan Adams <da...@ifactory.com>]

Select has hard-coded support for Enums and then defaults to strings.
Could we introduce a service that would allow registering values
encoders by type? I just hit a situation where I had to register an
encoder because my options were a list of booleans. Could also be useful
for lists of hibernate entities.

It's a bit inconvenient to have to add ValueEncoders for all the basic
wrapper types that are often in domain objects (Boolean, Integer etc.)
Howard's previous comment about translators applies here too:

"It does make sense that there should be a default translator that
leverages the TypeCoercer to perform translations to and from strings"

In fact I've added a JIRA issue:
https://issues.apache.org/jira/browse/TAPESTRY-1598

There's also a bug in automatic List to SelectModel conversion:
https://issues.apache.org/jira/browse/TAPESTRY-1597

Cheers,
Nick.

This is in 5.0.5, it's a new service called ValueEncoderSource. You
can map types to a ValueEncoderFactory implementation.
