AS3錯誤＃1007：實例化嘗試在非構造

Question

我得到標題錯誤，而試圖創建一個庫項目的實例：

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

我的跟蹤輸出正確類名，這也是庫鏈接（即com.age.AgegateInputView）。我想我失去了一些東西明顯...

編輯：是ApplicationSettings.AGEGATEVIEW指類：

    import com.AgegateSubmitAgeEvent;

所有的公共屬性都在組件的階段項目。在舞臺上進行測試時，該組件可以正常工作，只是動態地將其附加失敗。

Answer 1

相當愚蠢的人真的，忘記使用getDefinition。

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

Answer 2

任何機會，在你的ApplicationSettings.AGEGATEVIEW類，你要嘗試填充一個這樣的數組：

new Array[1, 2, 3]; 

，而不是正確的方法：

new Array(1, 2, 3);
