unpacking

[Paul Foraker]

Turns out the problem was in the calling handler, but this is a little
weird. When I reported just now that I'd fixed it by passing "j" already
prepended to the seconds, I had only tried that from the Message Box. Back
inside the calling script, it didn't work. Here's the calling script in a
button on a substack's card (faux dialog):

on mouseUp -- button on a card of sub stack "Days"
  get the selectedText of fld "DaysList"
  convert it to seconds
  put "j" & it into jDate
  close stack "Days" -- back on main stack "Journal"
  unpackTheData jDate
end mouseUp

That doesn't work. Even though jDate arrives at the main stack script with
the correct value, that value cannot be used to access the main stack's
custom property.

The unpackTheData handler does work, however, from the Message Box. That is,
I can pass "j"-something to the stack script and it will work.

So, it had to be the "close stack" command in the calling script. Sure
enough, this works:

on mouseUp -- in a button on sub stack "Days" of main stack "Journal"
  get the selectedText of fld "DaysList"
  convert it to seconds
  put "j" & it into jDate
  go stack "Journal" -- main stack
  unpackTheData jDate
  close stack "Days" -- substack cannot be closed prior to execution
    -- of a handler in the main stack
end mouseUp

I would call that a bug.
