Justin Edelson commented on SLING-5739:
---------------------------------------
[~henzlerg] this is actually about injecting a property of the child resource,
not the child resource itself.
For example, given the content structure:
{code}
- foo (nt:unstructured)
- jcr:content (nt:unstructured)
+ title (String) = "My Title"
{code}
If you want to adapt the node `foo` and have the `title` property injected.
Currently, to do this, you have to inject the `jcr:content` resource's ValueMap
and then manually extract the property.
> [Sling Models] Allow for extensible @Via providers

> Key: SLING-5739
> URL: https://issues.apache.org/jira/browse/SLING-5739
> Project: Sling
> Issue Type: New Feature
> Components: Extensions
> Reporter: Justin Edelson
>
> Currently, @Via support in Sling Models is limited to JavaBean properties. It
> would be useful to be able to extend this and allow for downstream projects
> to add new @Via providers.
> Proposing to support this by extending the @Via annotation
> {code}
> @Via(value = "jcr:content", type = ChildResource.class)
> {code}
> The default type is BeanProperty (the current behavior).
> New providers can be added by implementing a ViaProvider SPI and provide a
> marker class for use in the annotation.
