> ----------------------------------------------------------------------------------
>
> Key: SLING-4454
> URL: https://issues.apache.org/jira/browse/SLING-4454
> Project: Sling
> Issue Type: Bug
> Components: Scripting
> Affects Versions: Scripting Sightly Engine 1.0.0
> Reporter: Konrad Windszus
> Assignee: Radu Cotescu
> Fix For: Scripting Sightly Engine 1.0.0
>
>
> The {{org.apache.sling.scripting.sightly.use.UseProvider}} states in the
> javadoc:
> {code}
> {@code UseProvider} services are ranked according to the OSGi service
> * registration propertiy {@code service.ranking} which is an integer value.
> * {@code UseProvider} servies with lower ranking values are tried before
> * services with higher ranking values. The default value for the ranking if
> the
> * property is missing is zero.
> {code}
> All implementations like
> {{org.apache.sling.scripting.sightly.impl.engine.extension.use.JavaUseProvider}}
> and sibling classes state
> {code}
> @Properties({
> @Property(
> name = Constants.SERVICE_RANKING,
> label = "Service Ranking",
> description = "The Service Ranking value acts as the priority
> with which this Use Provider is queried to return an " +
> "Use-object. A higher value represents a higher
> priority.",
> intValue = 90,
> propertyPrivate = false
> )
> })
> {code}
> So what is true here? Are UseProvider with lower rankings queried first? What
> happens if they return a result.
> Please clarify the javadoc here.
