I am using JDK5, Eclipse3.4, JBoss Tools 3 Beta, JBoss Seam2.02 and JBoss AS 5 on Wondows. When I create a new Seam project everything is fine. But after I redesigned CSS and layout and a lot of others, the Richfaces UI components can't be displayed properly. toolbars and panels are displayed without background, items on tooolbar are placed closely together, there's no header in the top of a panel, those UIs have become plain. I used Firebug in Firefox to check CSS files with the web page, and found that there's not CSS file for toolbars and panels, however when such pages work fine I can see the 2 CSS files in firebug.
