Flex

flex 里 ：

 

• An ArrayList notifies its host component of any changes; the host component is updated immediately. Arrays do not provide any notifications of udpates.
• An ArrayList provides some tools for accessing data. Arrays provide only very basic methods and properties.

Array作为数据源时，如果更新了Array，Array更新后的数据不会在目标对象中显示 ，而ArrayList和ArrayCollection

是可以显示所做的修改的。

 

as to the HTTPService The URL that you specify for the HTTPService control is relative to the location of the HTML file that loads in your Flex application, not relative to the location of your Flex application's SWF file.
