Wow. Is that recent behavior? I've not been aware of the default* method convention before. Interesting indeed. Thanks for that!

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 "Computed Parameter Binding Defaults" section at http://tapestry.apache.org/tapestry5/guide/parameters.html).

Cheers,

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 nowhere in the select's source does the it access the ValueEncoderSource service. So, where/when/how does a default encoder get set?

Hi list,

Hi!

I simply want to know how the Select component gets its encoder from the ValueEncoderSource service, when an encoder isn't explicitly provided as a parameter. Thanks!

Are you using tapestry-hibernate? If yes, it provides ValueEncoder's using Hibernate's ClassMetaData class.
