      Description

      Description:

      When launching a Liveview enabled simulator session, it works as expected. When you attempt to rebuild the project again, the simulator fails to launch and this error presented:

      [INFO] :   Finished building the application in 1s 97ms
      [LiveView] Closing file/event server process id: 34204
      [INFO] :   Running application in iOS Simulator
      [LiveView] version 0.1.32
      [LiveView] File Server Started on Port 8324
      [LiveView] Event Server Started on Port 8323
      [INFO] :   Launching application in iOS Simulator
      [INFO] :   Focusing the iOS Simulator
      [ERROR] :  Failed to focus the iPhone Simulator window
      [ERROR] :  /Users/emerriman/Library/Application Support/Titanium/mobilesdk/osx/3.1.2.v20130807171139/iphone/iphone_sim_activate.scpt: execution error: iPhone Simulator got an error: Connection is invalid. (-609)
      [INFO] :   Application has exited from iOS Simulator
      [INFO] :   Project built successfully in 3s 58ms
      

      This occurs with both the iPad and iPhone simulators. The order of the console output may vary slightly.

      Also note that the behavior prevents the user from turning off LV and then launching on the first attempt. The first launch with LV off after encountering this error will fail with the same console output. The second launch with LV off seems to work fine. This may be a clue as to root cause.

      Steps to reproduce:

      1) Create a default classic project in Studio
      2) Enable Liveview and launch in the simulator
      3) Make some edits if you wish
      4) Relaunch the simulator - leaving liveview enabled

      Result:

      Project fails to launch correctly in the simulator. Turning off LV and launching will also fail, but will work on the next and subsequent launches with LV off.

      Expected Result:

      Project launches as expected and allows real-time editing

      Notes

      I monitored the processes here, and it may be expected but subsequent launches of Liveview were killing the existing node PID and launching a new one.
