Previewer never loads document.

[jrosengren]

I'm trying to get the Flash previewer to work in Share.  I'm using 3.2r and have OpenOffice 3 and swftools 0.9 installed on CentOS 5.4.

When I click on a Word document in Share, the document information page displays correctly, and the flash previewer loads correctly, however, the spinning progress icon inside the flash viewer never loads anything.  The flash viewer does seem to finish loading and display a preview for a PDF document.

This sounds like a problem with the process that sends Office documents to OpenOffice for transformation and then to swftools.  Is there any way I can diagnose this further since I'm not seeing anything in the logs while this is happening?

Thanks,

Just to confirm I see this also on 3.2r, running on Linux with OpenOffice.org 3.1.1 installed from the official tar.gz packet and swftools compiled from version 2009-08-24-2042

For example, I have one 6MB Word 2003 document with a lot of pictures which loads almost instantly - and then there's one 305KB Word 2003 document with just some text, and that never loads, the "progress circle" just keeps spinning..

I'd also like to know how to debug this.

You can raise the logging level on the org.alfresco.repo.content.transform package to try and see what's happening.

Sorry, I'm fairly new to Alfresco - can you post the magic incantation for doing that?

Thanks!

Thanks, Mike.  I'll do some logging and see what shows up.

I enabled DEBUG logging for the transform subsystem and this is what I see in the log for a file that never loads:

Here's what I see when I select a document that *does* load the preview:

I see a ton of other stuff at the end of the successful preview log entries, which I won't paste unless it looks necessary.

Any idea what's going on here?  Does it seem significant that the .docx file was successful while the .doc file wasn't?

Thanks,

– jeremy

[jrosengren]

Bump.

Any suggestions?  It'd be nice to have preview working for all documents.  If there's any other information I can dig up or things to try, I'm game.

[mikeh]

Nothing obvious in the log trace. Can OpenOffice (standalone) open the .doc file ok?

Thanks,
Mike

Right after bumping this thread, I went out to look for updates and noticed that 3.2 r2 was available.

I upgrade to 3.2 r2 and now the document previewer does finish loading, except that the now what happens is that the size of the window seems to be really, really large - you have to scroll all the way to the left and all the way up to see the document, which by default is extremely tiny.  Changing the zoom slider does work, although it resets the sliders on the previewer frame so that you have to scroll again to see the larger document.

So something in the latest build seems to have resolved the problem of the previewer never loading, but now doesn't seem to completely understand how to size the previewer window.

Has anybody seen anything like this with 3.2 r2?

Thanks!
