一个有问题的按钮权限控制：(一个角色只能控制一个按钮权限)
隐藏显示按钮：
Check Permission
1.新建一个角色
[Appearance("btnAuditWorkHourDisabled", AppearanceItemType = "Action", TargetItems = "btnAuditWorkHour", Enabled = false, Criteria = "Create_Uid.Roles[Name='AuditWorkHourRevocate'].Count<=0 ")] 缺点：角色名稱在程序中写死。
最好的方案用Expand中ActionState.
4.自己的实现方案(经简单测试通过)
在Main方法内加入： ((SecurityComplex)application.Security).IsGrantedForNonExistentPermission = true;
默认所以的Action是开启的，若想禁用请在角色权限加入拒绝即可。
