Carsten Ziegeler resolved SLING-4653.
-------------------------------------
Resolution: Fixed
I've added a new service property for the picker service, defaulting to false -
which was the initial behaviour.
Only if it is set to true the parent hierarchie is traversed - this is enabled
for the overriding picker
> [Regression] Merging resource provider is traversing parent hierarchy for
> finding hide properties
> -------------------------------------------------------------------------------------------------

> Key: SLING-4653
> URL: https://issues.apache.org/jira/browse/SLING-4653
> Project: Sling
> Issue Type: Bug
> Components: ResourceResolver
> Affects Versions: Resource Merger 1.2.8
> Reporter: Joel Richard
> Assignee: Carsten Ziegeler
> Priority: Critical
> Fix For: Resource Merger 1.2.10
>
>
> If the parent of one of the merged resources does not exist, but another
> resource between the merged resource of the same search path and root has
> some resource merging properties attached, these properties are ignored in
> MergingResourceProvider because resource.getParent returns null and then it
> does not try to traverse to root anymore and therefore does not find these
> properties.
> Example:
> /apps/a with sling:hideChildren=*
> /libs/a/b/c
> If you try to read /mnt/overlay/a/b, it will return null. On the other hand,
> /mnt/overlay/a/b/c will return an unmodified merged resource.
> *Important:* Consider the performance impact when fixing this issue. See
> referenced issue for more information.
