I can now properly mount an Alfresco Repository into the Document Library. However when I click the link for the newly mounted repository it displays the message "There are no documents in this folder." even though the Alfresco repository has documents.
If I click the Configure option on the Document Library and change the Root Folder to the mounted repository then the folders and documents will show up from Alfresco. If I try to open a document then Liferay completely crashes.
