When using the bulkimport tool Share fails to render imported documents when metadata has empty cm:creator or cm:modifier values. The files upload successfully however because you can view the expected folder contents in Alfresco Explorer. Within Share the only accessible files are the content uploaded within uploaded subfolders. You can see any subfolders when navigating using the tree view to the left in the Share folder view. The issue is replicated in Alfresco 4.1.9 and 4.2.4.
Steps to reproduce
Follow the documentation for importing using the user interface: http://docs.alfresco.com/4.2/concepts/bulk-import-via-the-ui.html
1. Extract the content of the .zip file attached to case
2. Navigate to http://localhost:8080/alfresco/service/bulkfsimport
3. Follow instructions for importing content from the folder.
User should be able to navigate via document library and view folders and files as they were in the content folder on the file system.
User is unable to view folders via document library, and only able to view files by navigating via the tree view or through Alfresco Explorer.
