Weird errors while trying to activate a font

Question

Hi,
I have a problem with Apple Script. Basically I need a script to check if a font is activated and if not activate it - this is because for some weird reason everythime I restart my Mac my Futura font family get's disactivated (various typefaces of this one family)
this is what I have so far:
tell application "Font Book" to tell font family "Futura"
    if enabled of typeface "Futura Medium" then
        set enabled of typeface "Futura Medium" to false
    end if
    if enabled of typeface "Futura Medium Italic" then
        set enabled of typeface "Futura Medium Italic" to false
    end if
    if enabled of typeface "Futura Condensed Medium" then
        set enabled of typeface "Futura Condensed Medium" to false
    end if
    if enabled of typeface "Futura Condensed ExtraBold" then
        set enabled of typeface "Futura Condensed ExtraBold" to false
    end if
    set enabled of typeface "Futura Medium" to true
    set enabled of typeface "Futura Medium Italic" to true
    set enabled of typeface "Futura Condensed Medium" to true
    set enabled of typeface "Futura Condensed ExtraBold" to true
end tell
It works quite well for the two first typefaces but when it gets to "Futura Condensed Medium" I get an error
"error "Font Book got an error: Can’t set typeface \"Futura Condensed Medium\" of font family \"Futura\" to true." number -10006 from typeface "Futura Condensed Medium" of font family "Futura""
Thanks in advance for any help because it's driving me crazy

Answer 1

I got the same errors as you when trying your script, and was unable to fix the issue. However, the following script, which uses GUI Scripting, seems to work pretty well under OS X 10.8.2. You must enable access for assistive devices in the Universal Access System Preference pane.
tell application "Font Book" to activate
tell application "System Events"
    tell process "Font Book"
        tell splitter group 1 of window "Font Book"
            delay 2 -- adjust if necessary
            select row 1 of table 1 of scroll area 1
            keystroke "f" using {option down, command down}
            keystroke "Futura"
            delay 1 -- adjust if necessary
            select row 1 of outline 1 of scroll area 2
        end tell
        tell menu item 10 of menu 1 of menu bar item "Edit" of menu bar 1
            if name begins with "Disable" then
                keystroke "d" using {shift down, command down} -- disable
                keystroke return
            end if
            keystroke "d" using {shift down, command down} -- enable
        end tell
    end tell
end tell
