             Summary: Sling Models Resource Child List Injector
                 Key: SLING-3516
                 URL: https://issues.apache.org/jira/browse/SLING-3516
             Project: Sling
          Issue Type: Improvement
          Components: Extensions
    Affects Versions: Sling Models Implementation 1.0.2
            Reporter: Igor Sechyn
            Priority: Minor


Hi All,

We have decided to use the sling models to process some hierarchical data in our project and are facing the following issue right now.

Our content structure looks as follows:
{code}
+- dealer
  |
  +- addresses
     |
     + -address1
     |
     +- address2
{code}
Dealer and address nodes have attributes, that can be injected through the ValueMapInjector, so everything works fine here. Our goal however is also to inject the List of AddressModel objects into the DealerModel object, something like this:

{code}
@Inject
List<AddressModel> addresses
{code}

The desired behavior would be:
- the injector resolves addresses as a child resource of the adaptable object
- iterates over the children of this resource (in this case „addresses")
- adapts each child to the actual type argument of the parameterized list type
- returns the list of adapted model objects

I have tried to play around with @Named but could not get it to work. The only way of making it work, was to write a custom injector, which worked out pretty fine. 

But I was still wondering, if there might be an OOTB functionality, which can be used for this use case

Cheers, Igor.
