> Conversion of context parameters to server-side objects uses type coercer
> rather than value encoders.

> Key: TAPESTRY-2177
> URL: https://issues.apache.org/jira/browse/TAPESTRY-2177
> Project: Tapestry
> Issue Type: Bug
> Affects Versions: 5.0.10, 5.0.11
> Reporter: Robert Zeigler
>
> TAPESTRY-2112 resulted in ValueEncoders being used to convert context
> parameters into strings for client-side representation.
> However, for form contexts, the strings are converted back into values via
> type coercion, rather than via ValueEncoder.
