NPE thrown when calling UIComponent.findComponent() with empty string id

    • Type: Bug Bug

    • Priority: Major Major
    • Resolution: Fixed
    • Affects Version/s: 1.0 Final

      Description

      There may be scenarios where a user wants to enclose all content (specifically contentStack/ContentPane) within 1 form tag. Currently the contentStackMenu will only work if a form tag directly surrounds it like so:

      <h:form>
      <h:panelGroup>
      <mobi:contentStackMenu>
      <mobi:contentMenuItem label="Menu" />
      <mobi:contentMenuItem label="Pane 1" value="panel1" />
      .............
      </mobi:contentStackMenu>
      </h:panelGroup>
      </h:form>

      If you were to move the closing form tag to the bottom of the page (below the contentPanes), the following NPE is thrown:

      java.lang.NullPointerException

      Test case demonstrating issue attached. Ready for deployment on Tomcat 7.

          MOBI-836 NPE thrown when calling UIComponent.findComponent() with empty string id

          • guard against all calls to UIComponent.findComponent() with a check for a null or empty string
