The fixed version of XWork changes the OGNL parsing so that it is not recursive. Therefore, in the example above, the result will be the expected %{1+1}. You can either obtain the latest version of WebWork 2 or Struts 2, which contains the fixed XWork library, or download the fixed XWork library directly. Alternatively, you can obtain the patch and apply it to the XWork source code yourself.
