[jira] [Commented] (SLING-2779) Support for default properties values of a resource

["Carsten Ziegeler (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-2779?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13745937#comment-13745937 ] 

Carsten Ziegeler commented on SLING-2779:
-----------------------------------------

I'm not sure about the "deletedProperties" part - does this mean you pass in a defaults map with a set of deleted properies and if the default map contains a property which is in the deleted set, this one is ignored? Why not simply removing the properties from the default map then?

For the location I think this makes sense to have it in the api bundle.

I'm not sure about the name, DefaultsValueMap - while it sounds fine it's similar to the CompositeMap (http://commons.apache.org/proper/commons-collections/javadocs/api-3.2.1/index.html).

> I already noticed several times it would be useful to be able to specify a default properties for a resource:
> * if the resource itself contains the property, it will override the default one.
> * but if it doesn't, the default value is used.
> This could be done either via:
> * specifying a {{sling:defaults}} property on the resource, which contains the path to the resource which properties will be used by default.
> * providing a default map of properties
> Attaching a patch for review.
> For testing purpose, I put it under {{org.apache.sling.defaults}}, but I imagine it could go to {{org.apache.sling.api.resource}}.
