      Dear all,

       

      we just started a new Java EE6 project with RichFaces 4.0.0. The first widget to implement happens to be the rich:accordion. However it only work when hardcoding the items. I would like to use it like that:

       

      <h:form>
          <rich:accordion>
              <ui:repeat value="#{navigationBean.navigationCategories.entrySet}" var="category">
                  <rich:accordionItem header="#{category.key}">
                      #{category.value}
                  </rich:accordionItem>
              </ui:repeat>
          </rich:accordion>
      </h:form>

       

      navigationBean.navigationCategories is a map (key: String, value: List). This will throw an exception:

       

      java.lang.NullPointerException

              [...]

       

      What am i doing wrong?
