Where is the button located? On the card? In a group?


This is the handler that it calls (I've xxxx'd out some domain details):

on updateSongsList
local songsOnDevice, songListOnServer
play empty
hide button "stopButton"
put "Checking for updates..." into field "messages"
put url "https://xxxxxxxxxxxx.com/hrabisms/songsupdate.txt"; into
songListOnServer
put the dgText of group "Songs" into songsOnDevice
if the number of lines in songListOnServer>  the number of lines in
songsOnDevice then
put "Update received!" into field "messages"
wait 120
set the dgText of group "Songs" to songListOnServer
set the defaultFolder to specialFolderPath("Documents")
put songsOnServer into URL ("file:songs.txt")
else
put "No update received. Rats." into field "messages"
wait 120
end if
put "" into field "messages"
end updateSongsList

I don't see anything untoward there. Something else is going on.

As I said previously, this script is not executed if it's in the card
script, but does when it's in the stack script. That's weird enough,

It's explainable if the button is farther back in the message hierarchy than the card. The message path gets a little convoluted in background groups.

but if I place it in the card script and I use "Send updateSongsList
to this card" in the button script it starts executing the card script
from the top, and I can track that by setting a breakpoint against the
send command - it jumps from the button script into the card script,
and I can step through all the lines in that card script, executing
them as I go.

Like I said, totally crazy!

Did you happen to insert the card script into the message path?

If it isn't already, try moving your button so that it sits directly on the card itself, not in any group. Keep its mouseup handler the way you have it above. That will put the card into the message path. Put your updateSongsList handler in the card.

I'm not sure what's going on, but it sounds like some kind of message path conflict coupled with some kind of recursion.
