Stuart Douglas commented on SEAMXML-21:
---------------------------------------
Currently you can do:
<x:balance>100</x:balance>
Also:
<x:balance><s:value>100</s:value></x:balance>
I am not sure if we really need three different ways of setting the field value.
> Field references should support value attribute
> -----------------------------------------------
>
> Key: SEAMXML-21
> URL: https://jira.jboss.org/browse/SEAMXML-21
> Project: Seam XML Configuration
> Issue Type: Feature Request
> Affects Versions: 3.0.0.Alpha3
> Reporter: Dan Allen
>
> Field references should support a value attribute if the field type is a convertable type* (Seam XML knows how to turn it into an object). This will drastically simplify the appearance and verbosity of a field definitions, particularly virtual fields.
> Consider the configuration of the default locale as an example. Presently, it would be configured as follows:
> <String>
> <Produces/>
> <lc:DefaultLocale/>
> <value>fr</value>
> </String>
> Since String is a convertable type, the proposed change would allow it to be simplified to:
> <String value="fr">
> <Produces/>
> <lc:DefaultLocale/>
> </String>
> Another example would be assigning an numeric value to a bean field. Presently, the configuration is:
> <x:Account>
> <x:balance>
> <value>100</value>
> </x:balance>
> </x:Account>
> With support for the value attribute, this could be simplified to:
> <x:Account>
> <x:balance value="100"/>
> </x:Account>
> If the type being configured has a value property, then of course the value attribute would assign the value of property named "value" instead of being treated as the overall value of the field.
> * Examples of convertable types are string, date, number, etc.
