Here is the situation: * On a MediaWiki 1.19.2/3 installed on a PHP server v. 5.2.17 and Validator 0.5.x installed, as well as SMW 1.8.0, we get this message on several semantic pages: Warning: file() [function.file]: Filename cannot be empty in /home/mysite/public_html/wiki/extensions/Validator/includes/definitions/ParamDefinition.php on line 956 This issue doesn't exist with Validator 0.4.13
This is an issue with the compatibility get_called_class. Don't know the source of the issue. Upgrading to PHP 5.3 will fix the problem. This code no longer exists on master, so wontfix.
PHP upgrade is unfortunately not up to me on this server. Too bad.
This becomes a support request. I opened a ticket at the following URL for further assistance: http://www.mediawiki.org/wiki/Thread:Project:Support_desk/Use_the_Validator_extension_in_MediaWiki_1.19
