    - #### getGxpInstance

          protected Object getGxpInstance()

      This implementation uses the `ObjectFactory` to try to create an instance of the `Interface` class that is nested within the GXP class. If that doesn't work, it falls back to trying to use the `ObjectFactory` to create an instance of the nested `Instance` class, in case there is no binding for the `Interface`.

        `getGxpInstance` in class `AbstractGxp<com.google.gxp.html.HtmlClosure>`
      Returns:
        Gxp instance
