关于wex.lib中的WindowsBase StackOverFlowException [英] About WindowsBase StackOverFlowException in wex.lib

问题描述

嗨！
我正在使用WPF可扩展性技巧或WEX-包括EventTrigger，ReactiveTrigger，InvokeMethodAction，InvokeCommandAction项目，您可以在代码项目中上载.出色的！！但是出事了我有一个复选框和一个组框，当IsChecked属性的myCheckbox为true时，我需要将GroupBox隐藏起来.但是当我运行应用程序(XBAP)时，抛出了异常

WindowsBase.dll上的StackOverflowException.我跟踪了源代码，并注意到这种情况仅在wex:PropertyTrigger情况下发生，并且在InvokeConditional(object parameter)中的EventBaseTrigger中引发了以下错误:

var result =参数为EventResult;
this.Sender = result.Sender;
this.Argument = result.Args; < ---抛出了异常

这是XAML的摘录代码

Hi!,
I''m using the WPF Extensibility Hacks or WEX - Includes EventTrigger, ReactiveTrigger, InvokeMethodAction, InvokeCommandAction project, you upload in code project. Excellent!! but something happen. I have a checkbox and a groupbox and I need when IsChecked property''s myCheckbox is true, GroupBox hide. But when I run app (XBAP), exception is thrown

StackOverflowException on WindowsBase.dll. I made a trace into source code and I note this happen just for wex:PropertyTrigger situation, and errors is thrown in EventBaseTrigger in InvokeConditional(object parameter) in lines:

var result = parameter as EventResult;
this.Sender = result.Sender;
this.Argument = result.Args; <--- Here exception is thrown

this is snipet code from XAML

<i:Interaction.Triggers>
    <wex:PropertyTrigger SourceType="Element" ElementName="chkMyCheckBox" Property="IsChecked">
        <wex:PropertyAction Action="Set" TargetType="Element" TargetName="grpMyGroupBox" Property="Visibility" Value="Hidden">
            <wex:PropertyAction.Conditions>
                <wex:InvokingConditions>
                    <wex:InvokingCondition Value="True"/>
                </wex:InvokingConditions>
            </wex:PropertyAction.Conditions>
        </wex:PropertyAction>
    </wex:PropertyTrigger>

感谢您的帮助！

推荐答案

XBAP应用程序是某些限制安全性的应用程序.

此问题可能是由于权限所致.

XBAP applications are some what limited security applications.

This problem could be because of Permissions.

感谢您的回复.我的情况发生在Anoop Madhusudanan在2010年1月14日开发的项目中.在Anoop开发的InvokeConditional(object parameter)方法中，将WindowsBase.dll中的异常引发到EventBaseTrigger中.
