大家好，

我在xmlview中定义了一个文本区域：

  </pre>
 <p>我可以在</p>中设置值
 <pre> onInit：函数（）{
 this.byId（" textAreaContent"）。setValue（" uschi"）;
 }，
 </pre>
 <p>这很好</p>
 <p>但是当我在下面使用相同的语句时，它不起作用，我想知道为什么</p>
 <p> <img src="/img/storage/temp/1687599-unbenannt.jpg"> </p>
 <p>我收到一个错误：</p>
 <p> <img src="/img/storage/temp/1687600-unbenannt.jpg"> </p>
 <p>谢谢。</p>
 <p>如何在对话框中使用setValue？</p>
 <p>谢谢，问候</p>
 <p>马里奥</p>
