Answer 1

make sure your script header contains things as following:

<s:Application xmlns:fx="http://ns.adobe.com/mxml/2009"
        xmlns:s="library://ns.adobe.com/flex/spark"
        xmlns:mx="library://ns.adobe.com/flex/mx">

Answer 2

If the Flash Builder project settings have the Flex Build Path configured with a component set of "Spark only" then MX components like <mx:DateChooser> will not be available. One way to fix this is to change the component set to "MX + Spark".

However, a trade-off of this approach is that the project will be able to compile a web application but not a mobile application. Another solution is to use a spark only DatePicker (actually, DateChooser and DateField). For example, here is an open source DateChooser component.
