From the filter I'm calling the SSB using Component.getInstance("myService", true). At first this failed on calling Component.getInstance throwing a IllegalStateException with the message "No application context active". I 'discovered' org.jboss.seam.web.ContextFilter and added it to my web.xml. The SSB is now called without problems. However, when the request returns to the ContextFilter it fails with another IllegalStateException with the message "No active event context".
