  Hi,

  You can tell DataTables what to do on error with the $.fn.dataTable.ext.errMode static property. There is some information about it available in the error documentation (the values it can take), but it really needs its own documentation page. I'll look into adding that!

  I had seen the error event documentation, it's triggered when the server gives an error, basically when things go out of control. I was looking for something to use when errors are caught by the server-side error handling routines.

  Perhaps DataTables could use something similar to JSON-RPC 2.0 response object. It uses either result or error to indicate success/failure. In DataTables, it could be the same, or to maintain backwards compatibility, it could be either "data" or "error".

  When successful, the server would respond:

  {
    "draw": 1,
    "recordsTotal": 57,
    "recordsFiltered": 57,
    "data": [
      ...
    ]
  }
  

  When unsuccessful, the response would be:

  {
    "draw": 1,
    "recordsTotal": null,
    "recordsFiltered": null,
    "error": [
      "code": -32601,
      "message": "Descriptive message about the error"
    ]
  }

  Oh - I see, sorry I misunderstood. If you send back an error parameter DataTables should show that.

  The $.fn.dataTable.ext.errMode could still be used with that (particularly is a non string error was returned) to do whatever display / update is needed on the client-side.
