Persons disappear when Scripting the Address Book

Question

If I modify the note of an Address Book entry via AppleScript, search no more finds this person.
This is how it goes:
Put following script in ~/Library/Address Book Plug-Ins/
using terms from application "Address Book"
on action property
return "phone"
end action property
on should enable action for thePerson with theEntry
return true
end should enable action
on action title for thePerson with theEntry
return "Test"
end action title
on perform action for thePerson with theEntry
copy the note of thePerson to aNote
set aNote to aNote & return & "Foo"
set the note of thePerson to aNote
end perform action
end using terms from
In AB make person Test Person, with mobile phone number and some text in note field.
Click the "mobile" tag, and choose action Test. "Foo" will appear as the last line of the note.
Click some other contact. Quit Address Book, and open it again.
Search field cannot locate Test Person any more!
The person still is in Address Book in its correct alpahbetic position.
The fix to the problem is to quit the Address Book and delete the file ~/Library/Application Support/AddressBook/AddressBook-v22.

Answer 1

Place the list in an address field, click the TO and change it to BCC.
If you do not have the Contact Sidebar turned on in the Write window press F9 to turn it on. Then select the contacts or list for the mail and use the Add to BCC button.
