Thank you Peter and Mark.
I guess I see it now - though it's still against *my* intuition :-)
Thanks
Alex.

I think that 'item 1 of t1’ has to be resolved to an object reference before it
can be used with the vis property. The earlier lines are doing that, but not
the last.
It seems that LiveCode has gotten stricter with this in recent versions,
requiring “of me” or such when referring directly to a control. Some later
version of 8.1 was breaking my existing scripts for this very reason.

OK, this code produces an error - but I can't see why (and I worry about that
:-)
I have a field inside a group inside a group ....,
and the following code :
on mouseup
local tName, t1, t2
put the long name of fld "F" into tName
put tName & ",12,13" into t1
put "t1" && t1 &CR after msg
put item 1 of t1 into t2
set the vis of t2 to TRUE
put "t2 was OK" &CR after msg
set the vis of (item 1 of t1) to TRUE
put "using parens OK" &CR after msg
set the vis of item 1 of t1 to TRUE -- this line fails !!
put "here" &CR after msg
end mouseup
that line fails, with the error message
button "Button": execution error at line 14 (Chunk: error in object expression) near "field
"F" of group id 1005 of group id 1007 of card id 1002 of stack "/Users/alextweedly/Dropbox
(Personal)/Apps/objectchunk.livecode"
I just cant see why that doesn't work :-)
If I use parentheses, or if copy the first item over to a different variable),
then it is all OK. But doing it directly (AFAICT) should work, and doesn't.
What am I misunderstanding ?
Thanks
Alex.
