             Summary: Apache Sling Content Editor contribution
                 Key: SLING-4001
                 URL: https://issues.apache.org/jira/browse/SLING-4001
             Project: Sling
          Issue Type: New Feature
            Reporter: Sandro Boehme


Based on the discussion at the dev list [1, 2] I would like to contribute the Apache Sling Content Editor (previously named JCRBrowser). 

++ Features ++
Currently it can be used to rename and delete nodes. Rename works by double clicking the node and you can multi select nodes for the deletion with the 'del' key. The node names are HTML and URL escaped and it provides stateless deep links to the nodes.

++ Further development ++
In the months to come I can work more intensely on the Sling Content Editor and I might add commercial add ons separately. This is why I would like to be able to point users to such an add on from Sling. But judging from other Apache projects [6] I assume this is probably not a problem.
I will continue the development at GitHub[7] and send patch files to Sling when new features are implemented.

++ Implementation ++
It uses the Sling API. 
For the tree on the left the JSTree library is used. It wants a URL to a JSON that contains the data for the child nodes. This URL points to a
Sling resource with a 'contenteditor.nodes' selector and a 'json'
extension. This way the JSPs [3] render the JSON for the resource that is consumed by the JSTree library.
For the deletion and renaming of nodes I use jQuery Ajax calls to the Sling POST servlet. 

The properties list on the right is rendered [4] using JSTL and the
currentNode variable of Sling.
The html.jsp is registered for the 'contenteditor' selector relatively to
the default servlet. And for not getting overruled by servlets
registered by paths and by other resources that are using the
'contenteditor' selector I use a ResourceDecorator [5]. 
I understand from Dominik Süß that I should use a ResourceProvider instead. I will work on changing that.

I'm looking forward to your feedback!
