Angular2/Nativescript:Strange“；“意外标记”；嵌套堆栈布局时出错

我正忙于Angular2 Nativescript应用程序，该应用程序在将输入字段移动到视图的另一部分之前工作得非常好，但在将输入字段移动到视图的另一部分之后，我发现以下错误，称为意外结束标记“StackLayout”。。。你知道这是什么原因吗？可以嵌套在彼此内部的堆栈布局的数量是否有限制？我移动到视图不同部分的输入字段是数量输入字段

我得到的错误是：

我在下面这行中遇到了相同的错误，这是使用字体时出错的原因

nt-awesome" text="

并尝试使用以下方法解决此问题：

这是您的问题：

 <StackLayout class="input-field">
       <TextField class="input input-border" hint="Enter Quantity" keyboardType="number" [(ngModel)]="qty">
 </StackLayout>

您忘记了结束标记

下一个结束标记是它抛出错误的

/StackLayout

，因为它与前面的

文本字段不匹配。
看起来您有一个或两个额外的`tags@mast3rd3mon您在哪里看到这些额外的stackLayout标记？每次它都显示
[错误->]
。要么是这样，要么就是你错过了其他东西的一个接近标签。你需要在这里包括屏幕，以便我们能够了解原因。根据错误mast3rd3mon可能是正确的，您可能在新的StackLayout标记中缺少一个结束标记，或者您有一个额外的结束StackLayout。您可以共享该组件的html吗？谢谢@Nathanel
