Description
The preview of files seems to work only partially. Most of the time it shows above error message or a red "x" in an empty box. Both, via preview tab and thumbnail. Strangely, it does work with some files. But i don't see a pattern which files (or file-types) work and which don't.

I have the similar looking problem, too. Creating of thumbnails is working, even if there are errors in log file like:
07.12.2014 21:08:38,852 WARN (com.logicaldoc.core.document.thumbnail.ThumbnailManager: 93) -- Error creating thumbnail for document: 3964929 Rechnung Anwalt
java.io.IOException: Thumbnail building Error in IMG to JPEG conversion
...

But the PDF-preview does only work vor ?.0 versions. In the log file for the preview creation LD is looking at the wrong path:
07.12.2014 21:08:38,860 ERROR (com.logicaldoc.core.store.FSStorer: 176) -- /usr/local/logicaldoc/docs/396/492/9/doc/1.1 (No such file or directory)
07.12.2014 21:08:38,860 ERROR (com.logicaldoc.core.store.FSStorer: 294) --

Is there probably a confusion between "version" (like 1.0, 1.1, 1.2, ...) and "file version" (like 1.0, 2.0, 3.0, ...). Because there is no need to create a preview of a version 1.1, because the difference between 1.0 and 1.1 is only meta information. The same file is stored, so of course the path .../doc/1.1 does not exist.

Please upgrade your system to version 7.1.2. Locate a document for which you don't see the previer and upload it here, so we can perform deeper investigation.
We cannot confirm the problem reported by jewgenij.tarschis since there is no confusion between document version and file version and the preview is only generated if the file version changes.
comment:6 by , 11 years ago
Yes, you're absolutely right, that the preview is only generated if the file version changes. But there is no change in the file version, because only some meta data changed (e.g. date or other attribute). If I want to view the preview, LD looks for the latest document version (e.g. 1.3). Since the latest file version is still 1.0 I can see some exceptions like I posted above.
I would like to try 7.1.2 but how to upgrade without losing database and documents? Nothing found in wiki or other documentation.

I don't need an upgrade package, but a kind of tutorial or how-to would be helpful (which files has to be replaced?).
Maybe it would be possible for community edition, too.

Sorry this is not possible, the Community is not directly supported so all kind of services require a commercial edition.

I've upgraded the system to version 7.1.2 now and after a change in the path configuration to Open Office the preview now works with almost every file type.
I still have problems with .tif files (neither preview nor thumbnail works) and .html files (only thumbnail works).

The tifs are previewed in general, please try the attached document for a working file. Unfortunately the tiff format supports a huge set of compression algorythms, maybe SWFTools was not able to convert that specific type of tiff you are using.
In any case we close this issue because of the preview works, then if you will have issues with tiffs, you will create a new bug dedicated to this.
Thi may depend if you have an updated OpenOffice installed in your server, we suggest you to use the latest OpenOffice 4.1. Basically LogicalDOC uses OO to preview your files you could check if OO is able to open those files.
