Why doesn't this simple applescript work any more in ML mail.app (as a rule)

Might it be that any incoming message doesn't have an ID yet ?

Try this:

using terms from application "Mail"

on perform mail action with messagestheMessagesfor ruletheRule

tell application "Mail"

repeat with theMessage in theMessages

display dialog "inside"

set theTest to (existsid of theMessage)

display dialogtheTest

end repeat

end tell

end perform mail action with messages

end using terms from

well, I noticed that if another display dialog is added just before the repeat loop, things seem to work correctly. I'm still working on the 'why' of it though.

ok, this seems to be a weird bug with placing the repeat command right after the tell statement. add any command between the two, or reverse their order, and it works again. for instance, this works on my machine:

using terms from application "Mail"

on perform mail action with messagestheMessagesfor ruletheRule

-- repeat first, then tell

repeat with theMessage in theMessages

tell application "Mail"

display dialog "inside"

set theId to id of theMessage

display dialog "the id is " & theId

end tell

end repeat

end perform mail action with messages

end using terms from

I don't see a rhyme or reason to it yet, but a workaround is better than nothing.

well, the other thing to try is to dereference the variables first. e.g.:

set theId to get (id of theMessage)

but it's possible that the headers simply haven't arrived by the time the script calls for them. I suppose you could set up a repeat/delay loop to wait for them, but it would be clunky. That would look like this:

repeat

try

set theId to get (id of theMessage)

-- if we get here, id has a valid value, so...

exit repeat

end try

-- otherwise delay/repeat

delay 0.2

end repeat

display dialog "the id is " & theId

Here is my solution:
