I installed a custom filter (@Filter(within = "org.jboss.seam.web.contextFilter")) and the filter is called as expected. I can also get and access the ThemeSelector via Context ctx = new SessionContext(new ServletRequestSessionMap(sreq)); ThemeSelector ts = (ThemeSelector) ctx.get(ThemeSelector.class); Problem is that I get a NPE when setting a theme. selectTheme throws | java.lang.NullPointerException | at org.jboss.seam.theme.ThemeSelector.select(ThemeSelector.java:87) | The annotations in my custom filter class are: @Startup @Scope(ScopeType.APPLICATION) @Name("de.dvdb.generic.seam.ThemeFilter") @Intercept(InterceptionType.NEVER) @Filter(within = "org.jboss.seam.web.contextFilter") Is this ok? - Chris View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080220#...
