[Content Manipulation][SlingPostServlet] Performing Multiple operations using Sling Post Servlet

[Nitin Nizhawan <nn...@adobe.com>]

Hi All,

   I have a requirement where I need to remove certain properties of a given node and also add some new child nodes to the same node, e.g. I need to transform node as in [1] to [2]. I am planning to use content manipulation operations of sling post servlet [3].
  
   For adding child nodes, import operation seems to work but for removing properties it seems I need to use default modify operation with "@Delete" suffix as the "@Delete" suffix does not work when specified within content JSON of import operation. 

Also, I would not like to touch properties which I do not intend to modify. E.g. in [1] I would not like to write to prop1 and prop2, so I do not have option to rewrite entire node.

So, I need to use two post requests to perform this complete transformation.
e.g. 
/path/to/node
1.  {"prop3@Delete":""}
2. {":operation":"import", ":contentType":"json",":content":"{childnode1:{cp1:'',cp2:''},childnode2:{cp3:'',cp4:''}}",":replace":true}


This seems to work but this does not happen atomically i.e. ajax in #1 may succeed and #2 may fail, which would lead to an inconsistent node structure for me. So, is there a way to perform both these operations in one sling post request?


[1] 
+ node
   - prop1
   - prop2
   - prop3

[2]
 + node
    - prop1
    - prop2
    + childnode1
       - cp1
       - cp2
    + childnode2
       -cp3
       -cp4
