> ---------------------------------------------------------------------------
>
> Key: SLING-8076
> URL: https://issues.apache.org/jira/browse/SLING-8076
> Project: Sling
> Issue Type: Bug
> Components: Feature Model
> Affects Versions: Feature Model 0.2.0
> Reporter: David Bosschaert
> Assignee: David Bosschaert
> Priority: Major
> Fix For: Feature Model 0.2.2
>
>
> When feature model extensions are merged via
> BuilderUtil.mergeExtensions(Feature, Feature,
> ArtifactMerge, BuilderContext) any merge extensions are only invoked when
> the second extension instance is being merged. The first extension is simply
> copied into the target.
> However the Merge Handler may also need to perform some action on the first
> copy, for example record what feature the extension came from. This is
> currently not possible.
> Proposal is to also call the Merge Handlers for the first merge (which is
> currently just a copy), so that they can also act in these cases.
