--------------------------------------

             Summary: NPE when trying to change the primary node type from 
nt:folder to sling:Folder
                 Key: SLING-3631
                 URL: https://issues.apache.org/jira/browse/SLING-3631
             Project: Sling
          Issue Type: Bug
          Components: IDE
    Affects Versions: Sling Eclipse IDE 1.0.0
            Reporter: Robert Munteanu


When trying to create the node type of an nt:folder to a sling:Folder using the 
JCR properties view, I get a NPE. Possibly related to the fact that there is no 
.content.xml for that node yet?
