Bug or feature?

Hello, I upgrade my xwiki from 0.9.840 (tomcat 4) to 0.9.1252 under tomcat 5.5. More or less it is running. But three things are not as before: 1. If I have a document called for example 'Doc.WebHome' the url in the generated html side is then '.../Doc/' without 'WebHome'. Is this a bug or a feature? 2. I get many velocity error messages like Velocity [error] RHS of #set statement is null. Context will not be modified. [line 6, column 1] What kind of log4j config line have I to do, to get more information, what's wrong? Currently I use the default skin! 3. If I go to a document (click on a link;-)) the whole document is shown, but after that the browser shows an active connection and is working several seconds before its finnished. This irritates a little bit and I don't see any reason why this happen. Has anyone see this behaviour by yourself? Thanks for your time! Bye Frank -- Dipl. Inform.
