Konrad Windszus commented on SLING-6652:
----------------------------------------
Registering multiple models on the same adapter is already supported via
http://sling.apache.org/documentation/bundles/models.html#specifying-an-alternate-adapter-class-since-110.
Maybe the same implementation picker can be used if multiple
resource-type-based model registrations exist. The default implementation
picker will always pick the implementation with the class name which comes
first in an alphabetical order
(https://github.com/apache/sling/blob/trunk/bundles/extensions/models/impl/src/main/java/org/apache/sling/models/impl/FirstImplementationPicker.java).
> Allow multiple adapters for Models with resourceType binding
> ------------------------------------------------------------

> Key: SLING-6652
> URL: https://issues.apache.org/jira/browse/SLING-6652
> Project: Sling
> Issue Type: Improvement
> Components: Extensions
> Reporter: Dirk Rudolph
>
> According to
> http://svn.apache.org/viewvc/sling/trunk/bundles/extensions/models/impl/src/main/java/org/apache/sling/models/impl/AdapterImplementations.java?view=markup#l59
> the AdapterImplementations support only mapping resourceType to Adapter 1:1.
> I would like to propose extending that to support 1:n binding between
> resourceType and adapter classes.
> My use case:
> Lets assume I want to combine my models with the exporter framework to export
> 2 representations of a single resource:
> * metadata
> * data
> To do so I would create 2 models, each bound to the same resourceType but
> annotated to be exported for different selectors.
