Viorel Lupu created SLING-8375:
----------------------------------
Summary: SlingPostServlet: :import operation must skip protected
properties if present
Key: SLING-8375
URL: https://issues.apache.org/jira/browse/SLING-8375
Project: Sling
Issue Type: Improvement
Components: Servlets
Environment: AEM 6.3
Reporter: Viorel Lupu
Attachments: error-import-json.log
h2. Description
Posting JSON content to the SlingPostServlet with *:import* operation as
documented at
[https://sling.apache.org/documentation/bundles/manipulating-content-the-slingpostservlet-servlets-post.html#slingpostservlet-operations]
fails when the JSON payload contains protected property names such as:
{code:java}
"jcr:createdBy",
"jcr:created",
"jcr:createdBy",
"jcr:baseVersion",
"jcr:lastModified",
"jcr:lastModifiedBy",
"jcr:uuid",
"cq:lastModified",
"cq:lastModifiedBy",
"cq:lastReplicated",
"jcr:versionHistory",
"rep:policy",
"onTime",
"offTime"
{code}
h2. Suggested Improvement
The importer should skip protected properties and proceed with import rather
than failing.
