I am, but that's not my question. My question is how does the select
component get a default value encoder when one is not provided as a
parameter? The source suggests it comes from the ValueEncoderSource
service, to which modules like tapestry-hibernate contribute. But

IIRC from browsing through the source code this is done automagically by
type coercing from your type to String (TypeCoercedValueEncoderFactory
or something). The correspondig Encoder is selected by the Select
components defaultEncoder() method, when no encoder parameter is
provided (see the
