when I click the Run button on the JSF: <h:commandButton id="searchButton" value="Run" action="#{columnsBean.viewRoles}"> the wrong method is being exec'd on the SFSB based on the output in the server.log. It's calling the getChoices() method in the SFSB when I click Run button. Why does this happen? seems like a bug. I will try with a fresh JBoss extraction... 2007-09-11 10:42:14,796 INFO [org.jboss.seam.example.booking.ColumnsBean] Retrieving all possible selections | 2007-09-11 10:42:14,796 DEBUG
