[jira] Commented: (SLING-1329) Multiple-value Reference Properties

["Felix Meschberger (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-1329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12805213#action_12805213 ] 

Felix Meschberger commented on SLING-1329:
------------------------------------------

Applied a fix in Rev. 903426 to try Resource.adaptTo(String[].class) if no adapter for String exists. This would be the case for a multi-value property.

> I am creating 2 node subtrees for two entities with a many-to-many relationship to each other.  I am implementing this relationship as a strong reference, multiple value property on each entity node under the subtrees.  I'm loading in the data as nt:unstructured with mix:referenceable as the only addition, so I can make references between the two.  The tree looks like this:
> /multiple-reference-property (root for this test)
>    |--users
>       |--user a(random uuid as its name)
>          |--regions-single (single property reference to region a, seems to work)
>          |--regions (multiple-valued reference property to regions a-e, renders fine as text but doesn't act as relationship if I try to traverse it via URL)
>       |--users b-e, set up identically to user a
>    |--regions
>       |--region a(random uuid as its name)
>          |--users-single (single property reference to user a, seems to work)
>          |--users (multiple-valued reference property to users a-e, renders fine as text but doesn't act as a relationship if I try to traverse it via URL)
> I can successfully use URLs like localhost:8181/multiple-reference-property/regions/<uuid to region a>/users-single.<json, xml, txt doesn't matter they all work>
> What does not work is a URL like localhost:8181/multiple-reference-property/regions/<uuid to region a>/users.<xml, json, doesn't matter none work>
> The data is loaded via a bundle, since using the contentloader with flat files will be unfeasible later in my project's future, because it will need a very large and randomized dataset, which only seems easily doable by directly interacting with the JCR api.
> Of course if there is a more preferred way to implement a relationship like this, please let me know.  I would strongly prefer to not use weak references in this case.
