I'm trying to evaluate using IntelliJ instead of Flash Builder as our Flex IDE. I have project with 4 modules where one is the actual main SWF app with the UI, and the others are SWC libraries containing business logic, styles, and assets.
Due to the history of this project we need to build it using the 4.6.0 SDK, with the "Use Flex 3 compatibility mode" enabled. This is a checkbox in the Flex Compiler settings in Flash Builder. How can I achieve the same setup using IntelliJ? Right now, I get errors such as these when I compile the main project: The style 'backgroundImage' is only supported by type 'mx.containers.Box' with the theme(s) 'halo'
Also, one of the other project always fail to build with a "Java heap space" error, i.e. running out of memory. I've tried bumping up "compiler heap size" to 1,400 MB to no avail. Any suggestions? I notice that the compiler runs a 32-bit java process. Is there a way to run it 64-bit mode?
