问题描述
在Beta1中，如果查询没有（对于用户）的权限，则基于显示的查询的屏幕"当前用户无权执行具有突出红色边框的命名查询"。
In Beta1 when there was no permission (for the user) for a query, A screen based on the query displayed 'the current user has no permission to execute the named query' with a prominent red border.
Beta2中的相同代码 显示'无法加载数据'或者我在Beta 1中硬编码消息（现在我的计算机上删除了测试版1）我不记得了。
The same code in Beta2 displays 'Unable to load data' or perhaps I hardcoded the message in Beta 1(now that beta 1 is removed on my computer) I do not recall)
推荐答案
如果有变化，它将不会是CanExecute方法，它只是修改了一个布尔值。
If there has been a change, it won't be to the CanExecute method, which simply modifies a boolean value.
屏幕对象*对CanExecute为false的反应方式可能已经改变了。我没有在B1中使用它，所以我无法确认这是否已经改变，抱歉。
The way the screen object *reacts* to CanExecute being false may have changed though. I didn't use it in B1, so I can't confirm if that has changed, sorry.
