Links to Help pages sometimes do not get generated

Dear OJS support team!

I'm having some problems with displaying Help pages after clicking Journal Help in the right-hand column. On some location on the website, the link to the appropriate help page doesn't get generated: the link looks like this: javascript:openHelp('http://www.ias-iss.org/ojs/IAS/help'), but on other pages the link is like this one: javascript:openHelp('http://www.ias-iss.org/ojs/IAS/help/view/user/topic/000001').

The first link ends with a 500 server error page, the second link displays context sensitive help.

Looking at the server error log it looks like the view() function in HelpHandler.inc.php is being called without the second parameter, $request.
The errors returned are:
Code: Select all
[Thu Sep 27 13:38:58 2012] [error] [client] ojs2 has produced an error\n  Message: WARNING: Missing argument 2 for HelpHandler::view(), called in /var/www/html/ojs/lib/pkp/pages/help/HelpHandler.inc.php on line 39 and defined\n  In file: /var/www/html/ojs/lib/pkp/pages/help/HelpHandler.inc.php\n  At line: 58\n  Stacktrace: \n  Server info:\n   OS: Linux\n   PHP Version: 5.3.3\n   Apache Version: Apache/2.2.3 (CentOS)\n   DB Driver: mysql\n   DB server version: 5.0.95, referer: http://www.ias-iss.org/ojs/IAS/about/editorialPolicies

I tried to see how the help function is called from problematic pages, but I couldn't find where the right column is generated, I have no idea what template I should look at. Two places, that generate errors after clicking on Journal help is the Article view page and some About pages (but not all).

I start noticing this after the upgrade of OJS to 2.4.0, but I'm not sure if the problem existed before - I just started to examine our server logs more closely now, after the upgrade, I ignored them before.

With kind regards,
Ales Kladnik

Thank you Alec, your patch solves the problem with missing help pages. However, the Help link from the article view page calls the main help page, not context sensitive. I don't know if it exists for that page, but the link generated is still javascript:openHelp('http://www.ias-iss.org/ojs/IAS/help'), doesn't end in specific codes like this link from the journal homepage: javascript:openHelp('http://www.ias-iss.org/ojs/IAS/help/view/user/topic/000001').
