It's just you, Jacque. I'm going back to bed.
Well, you're smarter than I am, because I've been at this for a couple
of days now without any progress. What I seem to be getting is lots of
empty status messages. What do those mean?
The things that could cause the message not to be sent that I can think
of:
An "unload url" or clearing of the pendingMessages after the message
has been sent but before it is handled. The likely place for this kind
of thing would be in the status callback handler. After a succesful
load, the final callback message gets sent just before the "load
message", both sent in 0 milliseconds. So if your callback handler does
one of these things when the status is "downloaded", the message won't
get sent.
So I'd look at the callback handler first.
I'm not doing either of those things so that isn't it.
What does it mean if the status is always empty? That is what I seem to
be getting. Then my status checking handler runs like mad but doesn't do
anything.
I've simplified my script a lot for testing. This is what I'm using at
the moment:
on downloadFile tURL
unload url tURL -- just for testing, so I can reuse it
load url tURL with message "saveFile"
get the result
if it <> "" then answer it
checkStatus tURL
end downloadFile
on checkStatus tURL
put urlStatus(tURL) into tStatus
if tStatus contains "loading" then
set the endValue of sb "progress" to item -1 of tStatus
set the thumbPos of sb "progress" to item -2 of tStatus
else
put tStatus
end if
if tStatus is not among the items of "cached,error,timeout" then
send "checkStatus" to me in 50 milliseconds
end if
end checkStatus
on saveFile tURL,tStatus
answer "SAVEFILE MESSAGE RECEIVED"
end saveFile
Nothing happens at all, except for the pending message that goes
repeatedly until I manually cancel it. Setting a breakpoint always shows
that tStatus is empty (which is why the script runs away with itself.)
The file doesn't come through usually. Sometimes it does.
It isn't my connection, because I can run RevNet or Eric's sample
tutorial and they work fine and their progress bars move. However,
neither of these use a callback message. I can make mine work too if I
don't use a callback message, and if I instead check for a "cached"
status and act on that.
Same behavior with any URL I try, including "http://www.google.com";, so
it isn't the URL. Also, same behavior if I comment out the "checkStatus"
call and just wait for a confirmation from "saveFile". I don't get one.
