Hi Ian, I debug the servlet from line to line and locate the NPE that causes this failure. The request path
SlingPostServlet > AbstractCreateOperation > ModifyOperation@line 105 where newResource = null. The resource resolver at this point is org.apache.sling.resourceresolver.impl.ResourceResolverImpl. 104 final Resource newResource = request.getResourceResolver().getResource(response.getPath()); 105 final Node newNode = *newResource*.adaptTo(Node.class); The resolver get a resource if the resource is already existing one(obviously). So either this should be a bug or my request goes through the wrong path. Please advice.
