Hello, I have installed xwiki 1.2 (MySql, Tomcat 5), and created a second blog following a suggestion in a previous postage to this list (by adding the $space variable to the blog macro). Everything seems to work just fine, but nevertheless I get error messages displayed on the Tomcat console, such as: 16:40:41,008 [http://iiscs.wssu.edu/xwiki/bin/view/Blog/] [http-80-Processor4] ERROR log.SimpleLog4JLogSystem - Left side ($bentrydoc.fullName) of '==' operation has null value. If a reference, it may not be in the context. Operation not possible. Blog.WebHome [line 20, column 28] It seems that the error is in the Blog.Macros' line below (I edited the original line to include $space): #if(($bentrydoc.fullName == $item)&& (!$space ||($space=="") || ($bentrydoc.getSpace()==$space)) ) Is it normal to get those kind of messages, and if not, is this a result of my modification, and how can I fix it? Since I don't really know Velocity, any advice will be highly appreciated. Thanks, Darina
