jQuery calls ajaxError even if server executes successfully

[sumanta]

Facing a strange behavior - we are using jQuery with Spring MVC at server-end. For a particular request, the call goes into ajaxError function even if there is no error seen in the server (infact, server executes successfully). Even more - the same call sometimes (rarely) executes successfully.

Hi

Can you provide a test case where this happens ?

I found this bug after I experienced a similar problem — a 2xx response from the server, but a call to the error function instead of success. In my case, the problem was that the content-type returned by the server wasn't what I was expecting, and didn't match what I had specified in .ajax's dataType option.

If you're still having problems, that might be something worth checking.
