Not able to Execute AppleScript within "Mail" application

Question

I have create one mail plugin and add "Button" beside the "Send" button of outgoing Mail,

and now i want to send outgoing Mail from my Button also and i also write applescript for that like

activate application "Mail"
tell application "System Events"
    tell application process "Mail"
        log "foo"
        tell menu bar 1
            tell menu bar item "Message"
                tell menu "Message"
                    click menu item "Send"
                end tell
            end tell
        end tell
    end tell
end tell

This script is working in Applescript editor but NOT WORKING FROM MY BUTTON CLICK

I have also execute applescript in Xcode like

NSURL* url = [NSURL fileURLWithPath:path];
NSDictionary* errors = [NSDictionary dictionary];    
NSAppleScript* appleScript = [[NSAppleScript alloc] initWithContentsOfURL:url error:&errors];
[appleScript executeAndReturnError:&errors];

And after execute the script i have getting Error:-

NSAppleScriptErrorAppName = "System Events";
NSAppleScriptErrorBriefMessage = "Can't get menu bar 1 of application process \"Mail\". Invalid index.";
NSAppleScriptErrorMessage = "System Events got an error: Can't get menu bar 1 of application process \"Mail\". Invalid index.";
NSAppleScriptErrorNumber = "-1719";
NSAppleScriptErrorRange = "NSRange: {0, 0}";

So I have tried all the thing But not get success.

So PLEASE HELP me to out this Problem

Thanks for any suggestion or help.

Answer 1

That menu item does have a keyboard shortcut, so you can use that too. Did you try this?

activate application "Mail"
tell application "System Events"
    tell application process "Mail"
        keystroke "d" using {command down, shift down}
    end tell
end tell
