---------------------------------------
Assignee: (was: Howard M. Lewis Ship)
> Scala style properties unnecessarily require a field with the same name
> -----------------------------------------------------------------------
>
> Key: TAP5-2016
> URL: https://issues.apache.org/jira/browse/TAP5-2016
> Project: Tapestry 5
> Issue Type: Bug
> Components: tapestry-ioc
> Affects Versions: 5.3.6, 5.2.5
> Reporter: Henning Petersen
> Labels: patch, scala
> Attachments: TAP5-2016.patch
>
>
> The changes introduced with TAP5-1064 allow Scala-style properties to be used
> from components without the need for Java-style getters and setters. The
> implementation currently requires a field of the same name as the property to
> exist on the bean, which is unfortunate.
> This works:
> var value: String = _
> <input ... t:value="value" />
> This does not:
> def value(): String = ...
> def value_=(value: String) { ... }
> <input ... t:value="value" />
> A class which delegates property access to a backing bean is not recognized
> by PropertyAccessImpl as having any valid properties; the same is the case
> when the field has a different name than the property.
> Possible workarounds include a dead field in the value class to satisfy the
> condition in PropertyAccessImpl, and adding Java-style getters and setters
> for the property.
