【问题描述】：

当我尝试在 BB Playbook 上运行显示 Cannot create property editable on qnx.fuse.ui.text.StageTextInput 的应用程序时，我不断收到错误消息。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 模拟器中出错。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"  softKeyboardType="email" />
    <s:Label text="Password" />
    <s:TextInput id="txt_password"  displayAsPassword="true" />
    <s:Button id="btn_login" label="Login" click="authenticate()" fontWeight="normal"/>
</s:VGroup>

还有堆栈跟踪：

【问题讨论】：

您使用的是哪个版本的 Flex？我认为 Playbook 还不支持最新版本的 Flex/AIR。如果您使用的是 Flex 4.6，我认为默认的 TextInput 外观使用本机文本控件 (StageText) 而不是“默认”Flex 控件 (TextField)。 [在 4.5 中不是这种情况]

我使用的是 Flex 4.6。我应该降级到 4.5 还是有办法让它使用 Flex 控件而不是本机控件？

我不确定。我能找到的最佳信息是 Playbook 还不支持 AIR 3 (supportforums.blackberry.com/t5/Tablet-OS-SDK-for-Adobe-AIR/…)。如果是这样，您将不得不降级，否则 Captive Runtime 可能会起作用。 “旧皮肤”应该仍然存在，因此您可以将皮肤类指定为 'spark.skins.mobile.TextAreaSkin'

【参考方案1】：

PlayBook qnx.fuse 组件不能在 Flex 中使用。

关于 Flex AIR 版本，我相信 PlayBook 实际上在 PlayBookOS 1.0.8 和 2.0.0 上支持 Flex 4.6 和 AIR 3

【讨论】：

我一直在 OS 1.0.8 上进行测试，AIR 版本是 3.1.0.20，但是我收到了上面发布的错误。
