Flex 4 & AIR 2 NativeProcess API: The NativeProcess could not be started

Question

I'm trying to build an application using AIR 2's new NativeProcess API's going from Brent's little video:

http://tv.adobe.com/watch/adc-presents/preview-command-line-integration-in-adobe-air-2

but I'm having some issues, namely I get an error every time I try to start my process.

I am running OS X 10.5.8 and I want to run diskutil and get a list of all mounted volumes.

Here is the code I am trying:

        private function unmountVolume():void
        {
            if(!this.deviceMounted){ return; }

            // OS X
            if (Capabilities.os.indexOf("Mac") == 0){
                diskutil = new NativeProcess();

                // TODO: should really add event listeners
                // in case of error

                diskutil.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onDiskutilOut);

                var startupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
                startupInfo.executable = new File('/usr/sbin/diskutil');

                var args:Vector.<String> = new Vector.<String>();
                args.push("list");
                //args.push(this.currentVolumeNativePath);

                startupInfo.arguments = args;
                diskutil.start(startupInfo);
            }
        }

which seems pretty straightforward and was based off of his grep example.

Any ideas of what I'm doing wrong?

Answer 1

The issue was that the following line was not added to my descriptor:

<supportedProfiles>extendedDesktop</supportedProfiles>

That should really be better documented :) It wasn't mentioned in the video.
