[solved] Download as pdf works but preview is not

[will]

Hello,

I've got this strange problem and couldn't solve it.
version is 6.3.0 community

Let's say I've got a png image or word document, I click on the "Download document as pdf" button and it works fine. If I look in repository/cache/pdf directory, I can see that it contains the correct uuid.pdf file. Then I click on the Preview tab and I have a window with "Conversion: Error: Couldn't open file '' ". My first guess was that pdf2swf did not work, but then if I look in repository/cache/pdf, I can see that the uuid.pdf file is still there but has changed! It is now a 4075 bytes binary file whatever the original was, and it appears than this is not a "real" pdf file so pdf2swf fails. Note that if I try again the "Download document as pdf" button it now fails as it try to read the bad pdf file in the cache.

I have spend a lot of time trying to identify the origin of this problem, but I don't know where to look to debug it. catalina.log contains info when pdf2swf fails but not with the creation of this 4075 bytes file. Openoffice, convert and ghostscript configuration seems to be good as the "Download document as pdf" button works in first attempt.

Hope someone encounters the same problem and solved it, or can give me some clues to log and debug this problem.

Will

Edit : Problem solved. There was an extra space in system.swftools.pdf2swf before the -f
/opt/openkm/tomcat/bin/pdf2swf -f -T 9 -t -s storeallcharacters ${fileIn} -o ${fileOut}

Thanks for your information. Althought in source code we could try to do some optimization to convert two or more spaces in a single one I do not know if it's a good idea on all cases. Meanwhile is not clear will continue as is now.
