启用EnabledEventValidation时,Firefox中的ViewState错误无效

Question

我有一个稳定的错误,每次击中F5时都会重现:

有两个网格(主 - 细节),当主网格上发生聚焦行更改事件时,我的客户端代码引发的回调实际上发生了错误.像这样的东西:

    this.mainGrid.ClientSideEvents.FocusedRowChanged = string.Format(@"
                function(s, e) 
                {{
                        if (typeof({0}) != 'undefined')
                            {0}.PerformCallback(s.GetFocusedRowIndex());
                }}",
                this.detailsGrid.ClientInstanceName);

这个bug只能在mozilla firefox中重现!(是的,IE没有问题,这有点奇怪=))

非常重要的是:只有当事件验证开启时,bug才会重现,即:

... EnableEventValidation="false" %>   // no error in this case

我建议原因是在必要的字段加载之前回调被触发(因为我得到它,事件验证使用一些隐藏的字段),所以我检查了使用setTimeout:

this.mainGrid.ClientSideEvents.FocusedRowChanged = string.Format(@"
            function(s, e) 
            {{
                window.setTimeout(function () {{
                    if (typeof({0}) != 'undefined') {0}.PerformCallback(s.GetFocusedRowIndex());
                }}, 2000);
            }}",
            this.detailsGrid.ClientInstanceName);

但是tat并没有帮助.2秒后,回叫开始,我收到错误.它仅在刷新时发生 - 第一次加载页面时不会引发错误.禁用网格的行缓存也没有帮助.需要帮助!=))

编辑:这是StackTrace

Edit2:' EnsureEventValidationFieldLoaded ' - 是的,我看到了这一点,但是...如果我等了2秒怎么能不加载？

编辑3:您可能会注意到这不是IIS问题(屏幕截图上为127.0.0.1 ip).

昨天我遇到了同样的错误,发现了类似的问题:http://sietch.net/ViewNewsItem.aspx？NewsItemID = 185

我目前的解决方法是:

$(document).ready(function(){
    $('#__EVENTVALIDATION').attr('autocomplete', 'off');
});

它似乎工作.但我还在测试.
