4WP Area and an attached reference to a container field

Has anybody noticed, that if a reference to an Write Pro container Field (Object or Blob) is attached to a Write Pro Area, the Write Pro Area object memorizes the name of that field given by the virtual structure (if virtual structure ist setup in the startup event). I would expect that a reference or token would be stored there in order to work language independent. The point is, if the virtual name and the real name are different, which is a usual case if a virtual structure is setup, the container field does not work at runtime. Is this a bug or is this topic to handle in a special way?
