Steps to reproduce:
1. Start a clean portal, login as "Test" user.
2. Create a folder in DM, add some documents in this folder.
3. Move the folder to recycle bin.
4. Click the folder in recycle bin.
Documents under the deleted folder can be seen and restored.
A message "This Documents Folder does not contain an entry." displayed.
Note: This works well in Portal 6.2.0-ce-m3.
