Change docStatus to invalidate entry when TU update
Map exception handler for failed file upload.

    There could be multiple causes for failed upload, so the best
    I can do for now is to append the exception message to a generic
    message. This is not ideal for localization, but is better than
    nothing and appears to be all that Seam will allow.
