I'm having some trouble with Flex code completion and error highlighting using IDEA v9.0.1 (93.94). I stripped a Flex module down to almost nothing and took the attached screenshot. IDEA code completion suggests s:Box and other options that aren't valid. If I choose (for example) s:Box from the code completion drop down, the editor will show 'all green' (no errors). I then have to re-import all Maven modules before it will correctly hightlight s:Box as an error.
I'm using Flex 4 (build 13555) and Flexmojos 3.4. Here is a POM snippet of dependencies in case it's useful:
I'm also having trouble with fx:Script tags inside of s:Application. See the second screenshot I've attached to see what I mean.
