    [CLOSED] Request Failure Window - Status code: Status Text: Communication Failure - 8.2

    I randomly get a popup window stating that <U>Communication Failure</U> has occured. This only happens when I use FireFox / Safari. I'm not sure why the error occurs because everything loads fine and the window disappears within a few seconds. There does not appear to be any failures. I do not get this message at all when using IE.

    I have tried suppressing the error message by setting the <U>ShowWarningOnFailure="false"</U> on the stores and AJAX Events. Is there a way to totally suppress this window.

    RE: [CLOSED] Request Failure Window - Status code: Status Text: Communication Failure - 8.2

    Hi,

    If you can reproduce that error with some code then please post it.
    You can totally surpress that window using the following script (for example, using DocumentReady listener of the ScriptManager)
    Coolite.AjaxEvent.showFailure = Ext.emptyFn;

    The error can be related with transport problem

    Hi Vladimir,

    I have the same issue as described in previous email. I realize this email thread is old, but since it's the same issue (please see attachment), can you please give me an example on how to suppress this window (global methodology if possible)? Thank you in advance for your help.

    Hi,

    Please clarify are you still using 0.8.x?

    If yes, did you try this?
    You can totally surpress that window using the following script (for example, using DocumentReady listener of the ScriptManager)
    Coolite.AjaxEvent.showFailure = Ext.emptyFn;

    Hi,

    Your case is different. You have server side exception (unfortunately, i don't see full text in window).
    I reccoment investigate that text and fix the server side exception.
    If the exception is expected then please set

    1. Set ShowWarningOnAjaxFailure="false" for ResourceManager (it turns off that window for all ajax requests)
    2. Set ShowWarningOnFailure="false" for DirectEvent (it turns off that window for particular request only)

    Hi Daniil,

    It's a long story that I rather not get into, but we're using a mixture of version 0.8 and 1.0. I haven't try the example you mentioned above since I'm not sure where I should apply it (page_load, page_init,???).

    Regards,

    Hi Vladimir,

    Is the example above apply to the page specifically? Or can it be use as a global methodology like setting it in the web.config file? I just want to make sure that I understood your suggestion above. By the way, I am currently have the following set in the web.config file under the <extnet /> tag

    ShowWarningOnAjaxFailure="false"

    But I am not sure it the correct place to set this.


    Thanks.

    1. web.config affects on the whole application (all pages).
    2. RecourceManeger affects on the current page only.

    I have a similar problem...

    Request Faliure.
    Communication Failure

    ONLY IN Firefox.


    Firebug says the error is in line:

    o.conn.send(postData || null);
    of
    function asyncRequest(method, uri, callback, postData) {
    .

    It happens after
     parent.window.location = url;
    Any idea?


    Thanks.

    Ok
    showWarningOnAjaxFailure="false"
    in web.config did the job, hopefully with no side effects.
