agreed. thought errors happen only with a single request, as mentioned in the docu. with multiple results i like an error too, but each response should be available. But how to return both? global is ugly.

I dont like lazy errors where something goes wrong, is not handled and plays domino-errors later. an empty result-set in sql is no error. a missing file is. a sql-rebservice should return an empty block then. errors are easily catched. easier than checking a result actually.
