I'm using idea 9.0.1 and I'm developing a flex application. My flex sdk version is 4.1.
I have the problem in code completion/error highlighting in mxml files:
when I use the flex 4 namespaces <s:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:mx="library://ns.adobe.com/flex/mx" ...>, in the mxml file I can't use code compeletion for <mx:.../> components and in editor all <mx:../> tags are highlighted as error, but when I use only mx namespace i.e. <mx:Application xmlns:mx="http://www.adobe.com/2006/mxml"> ..., the code completion is worked for <mx:.../> tags and there is no error highliting for <mx:.../> tags.
I would appreciate if you can help me
