Konrad Windszus commented on SLING-12245:
-----------------------------------------
Debugging revealed the following:
When renaming a working rewriter pipeline config from
{{/apps/system/config/rewriter2}} to {{/apps/system/config/rewriter}} the
following {{ResourceChange}} is received:
{code}
ResourceChange[type=ADDED, path=/apps/system/config/rewriter, external=false]
{code}
which is ignored in {{ProcessorManagerImpl.onChange(...)}}
However when renaming a working rewriter pipeline config from
{{/apps/system/config/rewriter}} to {{/apps/system/config/rewriter2}} the
following {{ResourceChanges}} are received:
{code}
ResourceChange[type=REMOVED, path=/apps/system/config/rewriter, external=false]
ResourceChange[type=REMOVED, path=/apps/system/config/rewriter/custom,
external=false]
{code}
which leads to removing the config at {{/apps/system/config/rewriter}} in
{{ProcessorManagerImpl.onChange(...)}} (in case it was previously registered).

> URL: https://issues.apache.org/jira/browse/SLING-12245
> Project: Sling
> Issue Type: Improvement
> Affects Versions: Rewriter 1.3.10
> Reporter: Konrad Windszus
> Priority: Major
>
> If one renames/moves a JCR node from {{/apps/my/config/invalid-rewriter}} to
> {{/apps/my/config/rewriter}} the new rewriter configuration is not being
> detected by the {{ProcessorManagerImpl}} due to the
> {{ResourceChangeListener}} only being configured to listen for changes below
> the {{rewriter}} resource
> (https://github.com/apache/sling-org-apache-sling-rewriter/blob/4d1952648e35e7001236f282040a78479f7726d4/src/main/java/org/apache/sling/rewriter/impl/ProcessorManagerImpl.java#L69).
