tabPanel causes NullPointerException if activeItem is not found --------------------------------------------------------------- Key: RF-10961 URL: https://issues.jboss.org/browse/RF-10961 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component-output Affects Versions: 4.0.0.Final Environment: RichFaces 4.0.0-Final Apache Tomcat 6.0.32 Reporter: Stephan Meisinger Priority: Trivial Fix For: 4.1.0.Tracking <rich:tabPanel activeItem="#{foo.tab}>...</rich:tabPanel> class foo { public String getTab(){return null;} } causes a NPE in org.richfaces.component.AbstractTabPanel (Line 64). This Bug was introduced with RF-10624. If activeItem is declared in a page, but Id not found getItemByIndex will return null, but return value is not checked. If bean return null, String is transformed by apache EL resolver from null to empty string (""). So res is also not null.
