      In one of our projects we extensively use the WebDAV-capabilities of Liferay. For performance reasons we decided to use the AdvancedFilesystemStore as backend for document library. If (and only if) the server is running on windows (Win7) with NTFS-filesystem, the checkin of a document often fails, with the result, that the document keeps checked out. (We use MS Office as WebDAV-Client). When switching to DBStore the issue disappears. When turning off the OpenOffice-preview (we use LibreOffice as is seems more stable) in backend the issue disappears as well. And finally on my developer-linux box, i've never seen this issue
      I'm not sure if i've seen this on 6.1.

      A further analysis of the problem shows that the method public boolean move(File source, File destination of the class {{
      com.liferay.portal.util.FileUtilImpl}} fails to rename the PWC-version to the final version of the document. This class makes use of the Apache Common IO (version 2.1) for their file-operations. But there is no problem, i think. In my opinion, the actual cause is that the PWC-version of the document is locked, while trying to rename it. A remote debugging session shows, that it is locked because liferay is generating previews from it in class com.liferay.portlet.documentlibrary.messaging.PDFProcessorMessageListener. This is explaining, why this only happens, when OpenOffice-previews are enabled.

      The preview generation takes some seconds depending on type and size of the document. During this time it is impossible to rename the PWC-file.

      A final test shows, that i might be right: i've saved the document in ms office manually and waited a couple of seconds before closing the document and finally i successfully checked in the document.

      I hope for some input from liferay devs, as this bug actually prevents productive use.
