The Flex team has started posting some free components on the Adobe Flex Exchange. The first one up is an auto-completing text input component. I haven’t looked at it yet, but it looks like it works the same way as a normal TextInput, with the addition of a dataProvider property that you can set to give it the list of possible completions. You can also specify a custom filter function that lets you implement other kinds of matching against the completion list (the default is to find entries with the user’s typed string as a prefix). Check it out!
