Minor Description
I'm on a fairly recent trunk build, and when I do save operations with the sling post servlet, I'm getting OK responses back from the servlet but I see errors in the sling log, and trying to retrieve the node again shows that the changes did not happen.
Here is one of the stack traces in the log
org.apache.sling.servlets.post.impl.operations.ModifyOperation Exception during response processing. javax.jcr.nodetype.ConstraintViolationException: Unable to perform operation. Node is protected.
