Try this:
view layout [t: text-list "hello" "there" "hello" "anton"]
(Now click on the first item)
>> t/picked
== ["hello"]
>> t/data
== ["hello" "there" "hello" "anton"]
>> find t/data t/picked/1
== ["hello" "there" "hello" "anton"]
>> index? find t/data t/picked/1
== 1
One problem with text-lists is that if you have
more than one item with an equal value, then
when you pick one, the other ones will also be
picked.
So it's good/necessary to ensure you have unique
values in your text-list.
eg. This list is problematic:
hello
there
hello
anton
If you pick the first "hello", the second one
will also be shown as selected, and vice versa,
if you pick the second one, the first one is also
shown as selected.
This means that if your values are not unique,
then it is difficult to find the index in the
series by using:
index? find series value
because you may have intended only the second
value to be picked.
A possible solution is to ensure your values are unique
by adding an index number to the beginning of each
string (or a number of invisible whitespaces at the end of
secondary instances of values).
