View Report - counting pdf views and article view inline pdf

Postby uko » Tue Nov 01, 2011 9:21 am

Hi all,

I discovered an issue with pdfobject and counting of pdf views in table article_galley when browsing with Firefox.
On article/view/articleId/galleyId with inline pdf: Each time using fullsize ON / Off a get request is called ('viewFile/articleId/galleyId'). Because pdf-view is incremented when requested 'viewFile ...' the counter is incorrect, and provides wrong user statistics therefore. I compared the report, generated by OJS, with the server log-file. My testcase shows significant differences.

I have no idea if it is a matter/bug of FF or of pdf-plugin or any other thing of jquery. Multiple get request only occurs in FF, not in Chrome or IE, I tested for comparing this behaviour.
Can anyone replicate it and confirm my observation, or is this only a strange behaviour within my test enviroment?

(It seems it would be more stable when counting pdf-views at first request of view/articleId/galleyId, see function view in ArticleHandler, not viewFile as it is in function viewFile in ArticleHandler. However, I am not gone deeper in source code (and I am not an expert), therefore, I know nothing about dependencies when code would be changed.)

test enviroment:
OJS resp OJS ,
win7 resp win server 2003,
php 5-2-9-2,
apache 2.2.11,
FF 7.0.1 ( with Adobe PDF-Plugin, vers resp FF 3.6.10 with Adobe PDF-Plugin, vers , IE8 ( with Adobe PDF Reader vers, chrome( with own integrated pdf viewer),

Hi Ute,

Thanks for the report! I've replicated this and have filed it as a bug report at http://pkp.sfu.ca/bugzilla/show_bug.cgi?id=6946. I've added a bit more debugging information to the report as well. Please feel free to CC yourself to that report for future updates, and/or contribute any other ideas or testing to that report or this forum thread.

we are using this statistics too.
Is there a workoround for this bug? When the bug would be fixed?
Best regards
K. Bretschneider

UPDATE 4.7.2012
I have tested on IE8, Opera 11.61 and Firefox 9.0.1 and on all Browsers are different behaviour to count the views in article_galleys table.
On Opera it was correct; on IE after clicking on the pdf-link (to go to the inline pdf-view site) the value increases +2 (!), but the clicks on FULLSCREEN and FULLSCREEN OFF did not increase the views anymore. On Firefox I had the same behaviour as Ute described.
