The latest IntelliJ build does not work in a usable manner with Flex 4.6.
I have made a new project based on template and everything (very standard).
First of all I get this message.
"[Flex46Test] Flex SDK 4.6.0 is not supported by built-in compiler shell. Please change compiler at File | Settings | Compiler | Flex Compiler."
(This menu option is not correct on Mac by the way. It's under the application menu -- IntelliJ | Preferences | Compiler ...)
Then second, after I changed this compiler setting (which gives distinctly less useful output, without clicking to errors et cetera):
1. On Linux I got a message: "Error in line 1: ( expected"
2. On Mac I get a message: "error while loading initial content"
I added a view which is set to navigator.firstView in a show event handler.
Now on Mac as well as Linux I get "Error: null"
Given my experience with previous Adobe SDK updates, I expect all the trouble to come from them. The upgrade from 4.5 to 4.5.1 was also absolutely terrible (back then I was using Flash Builder). Anyway, regardless of that, IntelliJ currently seems to be not usable with Flex 4.6.
