I was continuing to get the annoying bug about postponing rendering when trying to inherit the Reindeer theme in normal CSS. Every example I could find made it look simple, simply import the reindeer theme’s styles.css file. However, this. did. not. work. The debug window indicated there was a problem loading CSS. Well, chapter 8.4.2 of the Vaadin 7 book has a different example than everywhere else I found, and it works! Instead of importing the styles css file, you need to import legacy-styles.css, and that works!
