Why can't I import mx.controls into a Flex ActionScript project
apache-flex
Solution
To access mx libraries in an Actionscript Project, you need to point Flex Builder to the source path.
Right click on your Project -> Properties -> Actionscript Build Path -> Source path tab -> Add Folder... -> 'C:\Program Files\Adobe\Flex Builder 3\sdks\SDK_VERSION_NUMBER_HERE\frameworks\source\'
and now you can access all the mx.* classes.
Problem
I'm trying to do a simple import into an ActionScript Project that I've created in Flex Builder: import mx.controls.Label; It won't let me. Code hinting shows no 'controls' after mx. Any idea what's going on? Thanks.
