> <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.
