[jira] [Commented] (SLING-4915) Order of sub-nodes is not maintained in case of a merge

["Konrad Windszus (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-4915?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15140750#comment-15140750 ] 

Konrad Windszus commented on SLING-4915:
----------------------------------------

[~radu.cotescu] Which order should be taken in case  {{p2}} would not redefine all the children from {{p1}} but only few of them? Which order should be used then? Just take the following example 
{code}
/libs/p1/components/c1
  node1
  node2
  node3
/libs/p2/components/c1 (sling:resourceSuperType=/libs/p1/components/c1)
  node4
  node2
  node3
{code}

>             Project: Sling
>          Issue Type: Bug
>          Components: ResourceResolver
>    Affects Versions: Resource Merger 1.2.10
>            Reporter: Radu Cotescu
>            Priority: Minor
>             Fix For: Resource Merger 1.2.12
>
>
> Given two content structures that should be merged by the Resource Merger, if the second tree contains all the sub-nodes of the first tree, a new node added in the second tree will always be added towards the end, irrespective of its position in the sub-node tree.
> Example:
> {noformat}
> /libs/p1/components/c1
>   node1
>   node2
>   node3
> /libs/p2/components/c1 (sling:resourceSuperType=/libs/p1/components/c1)
>   node1
>   node4
>   node2
>   node3
> {noformat}
> When iterating over the child resources of {{/libs/p2/components/c1}}, {{node4}} will be the last child in the iteration instead of the second.
> The workaround is to not define the redundant nodes and add the {{sling:orderBefore}} property on {{node4}}, however this should be handled by default by the merger.
