- # Due to a bug in ZOOM-C (as of YAZ 2.1.38 of 31st October 2006),
- # diagnostics in Present responses are not reported, so that we
- # always end up in this callback rather than in error() where we
- # should be. Luckily, we can test whether the retrieval really
- # did work by rendering the record, which will yield an undefined
- # result if the fetch failed.
