I think this is not a good idea for autocompleter purposes. Autocompleter needs to be very fast. If you wait with next request until previous was completed, and, say, that previous request was dropped somewhere in the net, then you will wait long time, a few seconds at least until it will time out. The better approach is to identify each request with some unique id, maybe a serial number, and check if the response you just received is the response for the last sent request. If the responses are deterministic, then parameters of request are sufficient id, if not, then you need a unique identifier. I personally use Ajax.Request for this purpose. I add a serial number to parameters, and, at server side, I put the serial number to the X-JSON: header, along with status (such as error codes, if any, or success indicator etc). Then in the onComplete I check the header only. But this is only possible if you have control over serverside script. I haven't any need to access the request object from the response one, but I always thought it was available as a parameter of the Ajax.Response object [1]. Richard, As for the bug, maybe it's worth submitting the patch again to the Lighthouse [2], as the Trac is used no more. 1. http://prototypejs.org/api/ajax/response 2. http://prototype.lighthouseapp.com/ Best Regards, SWilk --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Prototype & script.aculo.us" group.
