Maybe if you execute the upload document method through a smartobject event on a workflow, I'm not 100% sure though.

Hi Ziqing,

Thanks for your answer. The problem is that we also want to allow users to list, download and upload documents in Sharepoint through K2 Smartforms so we can't restrict to execute smartobjects in the workflows.

Any other idea?

Thanks!

The only way to do it with the out of the box app would be the way Ziqing just described as doing it from a workflow would result in the service account performing the operation.

The app is hard coded to enforce impersonation to a list/library so if that user doesn't have access they won't be able to do anything.  Is the end goal just to have the documents reside in a library that no other users have permission to?  If so, you could use two separate libraries.  The users would have access to the first document library so they can upload/list documents and then have a workflow on the backend that moves the documents the desired document library where the users have no access.

Thanks,

Jimmy
