Open GC window in one .applescript file and work with it in another

Scripting Forums AppleScriptObjC and Xcode
#1

Hello!

I’m trying to open Google Chrome in my app and run a test suite on it.

I have two .applescript files in my project:

AppDelegate

script AppDelegate
	property parent : class "NSObject"
	
	-- IBOutlets
	property theWindow : missing value
        property AnotherAppleScript: missing value
    
	on applicationWillFinishLaunching_(aNotification)
            set newWindow to (current application's AnotherAppleScript's launchGoogleChrome())
        
            tell application "Google Chrome"
                set windowID to id of newWindow
                set URL of (its window id windowID)'s first tab to "http://example.com"
            end tell
	end applicationWillFinishLaunching_
	
	on applicationShouldTerminate_(sender)
		-- Insert code here to do any housekeeping before your application quits 
		return current application's NSTerminateNow
	end applicationShouldTerminate_
	
end script

AnotherAppleScript

script AnotherAppleScript
  
  property parent : class "NSObject"
  
  on launchGoogleChrome()
      tell application "Google Chrome"
          set newWindow to make new window with properties {mode:"normal"}
          return newWindow
      end tell
  end launchGoogleChrome
end script

I receive this error:
2018-12-13 14:11:44.963858+0400 Test[52350] *** -[AppDelegate applicationWillFinishLaunching:]: Can’t get id of «class ocid» id «data optr00000000C08B2F0000600000». (error -1728)

Why?

Everything is fine if I try to do it in one file.

You can’t return AppleScript objects from methods that are called by another object in an Xcode app. You’re effectively calling an Objective-C class method on an Objective-C class (AnotherAppleScript), and the method must return a Cocoa object.

Try passing the window’s id instead; the scripting bridge can then wrap that in an NSNumber. Just remember to coerce it back to an integer in the calling code.

Oh thank you very much, it works!
