on oneButtonClicked_(sender)
    set faceNumber's setStringValue() to faceNumber's stringValue() & "1"
end oneButtonClicked_

I get this error: "Can’t make «class ocid» id «data optr000000000058B37BFF7F0000» into type list, record or text. (error -1700)"

faceNumber is a label and when the user clicks the button, I want to add string of "1" to it. So for example, if the user clicked the button 5 times

stringValue returns an NSString(wrong answer) CFString. You have to make a real AppleScript String to use it. BTW your code set faceNumber's setStringValue() is not correct. The reasons are:

  1. The Cocoa handlers are always using the underscore.
  2. If you use the setter setStringValue() you don't need to use set x to
  3. If you want to use setStringValue() you must give the parameter between the parentheses

Now put everything together:

on oneButtonClicked_(sender)
    faceNumber's setStringValue_((faceNumber's stringValue) as string & "1")
end oneButtonClicked_

or (to have it clearer):

on oneButtonClicked_(sender)
    tell faceNumber
        set currentValue to (its stringValue) as string
        setStringValue_(currentValue & "1")
    end tell
end oneButtonClicked_

I hope you like the answer, after pressing the button twice you have an 11 at the end of the label.

  • Thanks! So when I have an NSString, I have to convert it to an AppleScript string to use it? – James Nov 15 '14 at 18:43
  • In fact you get a CFString (my answer is wrong at this point) and have to convert it to an AppleScript string. – ShooTerKo Nov 15 '14 at 23:21
