Transport error - HTTP code: 12019

[buddhikasgj]

SmartGWT version : v9.1p_2015-02-14/Enterprise Deployment (built 2015-02-14)

Browers: IE 11

Test Case: time to time our application encounter below exception in ie 11.



This is specially when we perform any operation which triggers dsRequest from browser to server and perform another UI operation without waiting for the response of the previous dsRequest. when this happens, using developer tool bar we can see the http request is aborted by the browser. As i understood this kind of scenarios can happen in any moment in an ajax based application. So is there any solution at the smartgwt framework level to handle this kind of scenarios.

Any kind of advice,suggesion is highly appreciated.

The entire series of 120xx error codes are bogus error codes, used only by IE, which indicate some internal error within IE has occurred. The particular one you are getting indicates that some code within IE has misused low-level networking APIs.

First of all: are you really getting this in IE11? If so, are you using meta tags that ask IE11 to emulate an older version of IE? Because one can find quite a few people saying that this category of error was eliminated in IE10.

Second, you are talking about aborting a DSRequest - what specific component issued the DSRequest and how is it being aborted? Please be very specific. The best way to avoid this error is probably going to be to either correct usage issues in your code, or reorder operations to avoid it, and if you continue to be vague about what you are doing, no one will be able to provide meaningful advice.
