当我尝试在 BB Playbook 上运行显示Cannot create property editable on qnx.fuse.ui.text.StageTextInput. 完全相同的代码在 Android 和内置模拟器的 Flash Builder 上运行良好，但在物理 Playbook 和 Blackberry Playbook 模拟器上出错。似乎导致错误的代码区域如下：
<s:VGroup includeIn="login" top="10" left="10" right="10" id="loginForm">
<s:Label text="Email" />
<s:TextInput id="txt_email" width="100%" softKeyboardType="email" />
<s:Label text="Password" />
<s:TextInput id="txt_password" width="100%" displayAsPassword="true" />
<s:Button id="btn_login" label="Login" click="authenticate()" fontWeight="normal"/>
</s:VGroup>
和堆栈跟踪：
ReferenceError: Error #1056: Cannot create property editable on qnx.fuse.ui.text.StageTextInput.
