Nativescript自定义对话框异常

Question

我试图通过遵循this example在nativescript（角度2）中获得自定义对话框模式弹出窗口。

任何想法，为什么点击SHOW按钮，我得到下面的异常时：

EXCEPTION: No component factory found for DialogContent (d:\npn\qwe\node_modules\@angular\core\bundles\core.umd.js:3462:27) 
ORIGINAL STACKTRACE: (d:\npn\qwe\node_modules\@angular\core\bundles\core.umd.js:3467:31)

Answer 1

我找到了解决办法在another so.在主模块必须添加：

@NgModule({ 
    .... 
    declarations: [ DialogContent ], 
    entryComponents: [ DialogContent ] 
})
