當我嘗試在BB Playbook上運行一個名爲Cannot create property editable on qnx.fuse.ui.text.StageTextInput的應用程序時，我總是收到錯誤消息。在Android和模擬器中內置的Flash Builder中，相同的確切代碼可以正常工作，但在物理Playbook和Blackberry Playbook Simulator中出現錯誤。的代碼，這似乎是導致錯誤的區域如下：無法在黑莓應用程序中創建文本輸入
<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>
而且堆棧跟蹤：
ReferenceError: Error #1056: Cannot create property editable on qnx.fuse.ui.text.StageTextInput.

您正在使用哪個版本的Flex？我不認爲Playbook支持最新版本的Flex/AIR。如果您使用的是Flex 4.6，我認爲默認的TextInput皮膚使用本地文本控件（StageText），而不是「默認」Flex控件（TextField）。 [4.5中並非如此] – JeffryHouser 2012-02-08 18:44:19
我在Flex 4.6上。我應該降級到4.5還是有辦法讓它使用Flex控件而不是本地控件？ – 2012-02-08 19:38:15
我不確定。我可以找到的最佳信息是，Playbook目前不支持AIR 3（http://supportforums.blackberry.com/t5/Tablet-OS-SDK-for-Adobe-AIR/Tips-Definitive-guide-to-AIR- apps-for-playbook/td-p/1080047）。如果是這樣，您必須降級，否則Captive Runtime可能會起作用。 「舊皮膚」應該仍然存在，所以你可以指定皮膚類爲'spark.skins.mobile.TextAreaSkin' – JeffryHouser 2012-02-08 20:06:50
