AS3 错误 #1007：在非构造函数上尝试实例化

Question

我在尝试创建库项目的实例时遇到标题错误：

trace(ApplicationSettings.AGEGATEVIEW);
var clazz:Class = ApplicationSettings.AGEGATEVIEW as Class;
ageGateForm = new clazz();

我的跟踪正确地输出了也是库链接的类名（即 com.age.AgegateInputView）。我想我遗漏了一些明显的东西......

编辑： ApplicationSettings.AGEGATEVIEW 所指的类：

package com

            }
        }
    }
}

所有公共属性都是组件舞台上的项目。该组件在舞台上测试时工作正常，只是动态附加它失败了。

Answer 1

在您的 ApplicationSettings.AGEGATEVIEW 类中，您是否尝试像这样填充数组：

new Array[1, 2, 3];

而不是正确的方式：

new Array(1, 2, 3);

Answer 2

真的很蠢，忘了用getDefinition。

var clazz:Class =  ApplicationDomain.currentDomain.getDefinition(ApplicationSettings.AGEGATEVIEW) as Class;
