From the docs: "If the field is a card field (not part of a group),
its sharedText property has no effect."
Which we now know is not strictly true. Which suggests that what
we're seeing is some kind of side-effect, so maybe not to be relied
upon.

Hi,
I just dug up the test stack and verified that EITHER the Shared
Text property OR using the long id form of the reference works. e.g.
If sharedText = false then
put "XXX" into me
else
set the text of the long id of me to "XXX"
end if
works ok if sharedText = true or false. If course the:
set the text of the long id of me to "XXX"
works regardless of the setting of sharedText, but is slower.
It's really difficult to know what to do for the best here. Is this
a side-effected action of sharedText or it be relied on to work
forever? Or should I go for the long hand safer (hopefully?) code
that runs slower? If I have to design 50 windows for an application
it's a question I think I would like to know the answer to before
doing much coding!

Hi,
The secret was revealed by finding out that if you set the "shared
text" property of the field all works ok, e.g. put "x" into me work
as expected, there seems to be a "ghost" context in which "me" is
not actually me, or the context gets restored back to it's former
state IF the shared text property is off. However I'm not sure if
the shared text property is just causing a side-effect that may
well change in future releases so I have used the long hand form
(which takes longer to execute.
Which version of RunRev are you using and which platform(s)??

If I add "select the text of me" to the script of the field on cd
2, and I press the button on cd 1, I get this error:
Chunk: can't select object that isn't open
Which is perhaps some sort of clue. However, if there is some text
in the field on cd 2, and you change it's script to
on messageY
put me
end messageY
press the button on cd 1 and it happily puts it's contents into
the message box.
So it seems hard to see exactly when we can use "me" and when we
can't.
It seems to work in accessing a closed objects own properties --
the long id of me, in your work around -- but not in setting them.
However, if we now change the on messageY handler to
set the height of me to the height of me * 2
and press the button on cd 1, go to cd 2, the field is twice as tall!
So that theory goes out the window!
Perhaps this "me" trouble is confined to the text of fields?
Whether or not this is a bug, it seems to me an ideal subject for
some sort of Wiki - I don't know if RunRev have theirs up and
running, yet. They didn't, last time I looked.
I also think there may be a good argument for having special
sections in the Docs that deal with these "me", "it", "the result"
words, which do seem to get confusing, at times.
yes, and add something on the shared text property too.
Best,
Mark

Hi,
I thought I'd re-visit this as people seem to be in the mood for
bug fixing or changing documentation. How should this be filed?
I'm really not sure what needs to be changed, I have listed the
work arounds I have found at the end. I would suggest that at the
very least this is mentioned in the PDF and the Online Docs.

I have a Stack, StackMain.
In StackMain Card 1, I do:
-- On a field
on MessageX
put "MessageX" into me
end MessageX
-- on a button
on mouseUp
send "MessageX" to field 1 of card 1 of stack "StackMain"
send "MessageY" to field 1 of card 2 of stack "StackMain"
end mouseUp
In StackMain Card 2 I do:
--On a field
on MessageY
put "MessageY" into me
end MessageY
--on a button
on mouseUp
send "MessageY" to field 1 of card 2 of stack "StackMain"
end mouseUp
If I press the button on Card 1, then MessageX gets called in
Card 1 ok and the field gets set to "MessageX". All is fine.
MessageY in Card 2 field 1 gets called ok too, BUT the field is
NOT set to "MessageY" as expected????? However if I select card 2
and then press the button in Card 2, again the MessageY in Card 2
field 1 gets called AND the field is set ok. All is fine.
It seems like the following path does not work:
Card 1:Button 1:mouseUp -->Card2:field 1:MessageY does not work.
But
Card 2:Button 1:mouseUp -->Card2:field1:MessageY works fine.
The weird thing is that the handlers do get called and I have
stepped over the statement that does:
put "MessageY" into me and that seems to work. However, when you
select card 2, the field has not been changed.
--------------------------------------------------------------------
-----------------------------------------------
KNOWN WORK-AROUNDS:
--------------------------------------------------------------------
-----------------------------------------------
1. Instead of using the form:
put "MessageY" into me
Use:
set the text of the long id of me to "MessageY"
2. Set the Shared Text Property in the property inspector of the
field.
Easy to solve, VERY HARD to TRACK DOWN!!!!!!!!!!!!!!!!!!!!
