  • 使用Flex4的PopUpManager的addPopUp() 方法弹出 removeChild异常的解决办法

    Flex4中,弹出窗口有两种:

    Alert.show("balabalabala…");

     

    PopUpManager.addPopUp([要弹出的控件],[父控件],[是否模态]);

     

    第二种是我们最常使用的,却很容易出现问题(如题)。

    出现的原因是因为使用了spark组件,因为spark组件没有removeChilde的方法,

    所以就产生了异常。这是adobe的BUG,目前还没解决。

    规避的办法就是将需要弹出的控件放置在mx组件内部即可。

    附原始英文解释:

    There is a problem in Flex 4 when you using the PopUpManager's addPopUp() method to

    create a pop up that has a Spark container parent. This problem was reported in a JIRA bug:

    SDK-25082. If you call addPopUp(), you will get the runtime error:

     

    Error: removeChild() is not available in this class. Instead, use removeElement() or modify

    the skin, if you have one.

    at spark.components::Group/removeChild()

     

    Unfortunately, we didn't have time to fix this bug in the Flex 4 time frame. So, the bug was

    deferred. However, there is a pretty simple workaround for the bug. In your code, you just

    need to parent the component that you want to pop up with an MX component.
