There's a problem in Alfresco community 5.2.
I found some file links whose destination is NULL, and try to delete those, but failed.
"Force delete" on nodebroser doesn't work with below error.
050729912 Property 'nodeRef' has not been set: org.alfresco.repo.doclink.DocumentLinkServiceImpl@46666a9c (class org.alfresco.repo.doclink.DocumentLinkServiceImpl)
Can somebody help me?
