---------------------------------------------------------------

                 Key: RF-10961
                 URL: https://issues.jboss.org/browse/RF-10961
             Project: RichFaces
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: component-panels-layout-themes
    Affects Versions: 4.0.0.Final
         Environment: RichFaces 4.0.0-Final
Apache Tomcat 6.0.32
            Reporter: Stephan Meisinger
             Fix For: 4.0.1.Milestone1


<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 is 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.
