set SetA to {"a", "b"} -- elements for set A
set SetB to {"c", "d", "e"} -- elements for set B and so on....
set foo to union(SetA, SetB)
to union(a, b)
if (class of a is not list) or (class of b is not list) then
display dialog "Only lists can be used." buttons {"Cancel"}
default button 1
end if
if (count (a)) is greater than (count (b)) then
copy a to x
copy b to y
else
copy b to x
copy a to y
end if
set FinalResult to y
repeat with i in x
if (i is not in y) and (i is not in FinalResult) then
copy i to end of FinalResult
end if
end repeat
end union
But with Script Editor 2.0 beta, the result is:
{"a", "b", item 1 of {"c", "d", "e"}, item 2 of {"c", "d", "e"}, item 3
of {"c", "d", "e"}}
And with Script Editor 1.9, the result is:
item 3 of {"c", "d", "e"}
What is going wrong here?
