NPE thrown when accessing a folder in TouchUI Assets (DAM)

Avatar

Level 4

I can't figure why this Null Pointer Exception is getting thrown when a user try to access a folder in the dam. I am logged in as admin and this folder was working yesterday. This is only occuring on our QA server. The dev server has the exact same code package and the folders work. QA is open to regular content authors, so I'm wondering if a user screwed something up.

I had to truncate error log, but I think this should be enough.

I was able to solve with help from Rackspace CAS. Apparently the jcr:primarytype of the folder needs to be sling:OrderedFolder and not sling:Folder

squid267​ - Could you please help me with the steps.

Even though I see the similar NPE, but jcr:primarytype of my asset folder is sling:OrderedFolder.

The error:
