How would you create the array programmtically
ie. values array needs to be populated via data
values sourced elsewhere ( and typically available
in a string variable) rather than from a static list.
Thanks

Hi Derek,
As far as I can remember you just need to set the multi-value widget
value to a simple array, and I don't think you should initialise the
array with 10 values if you are only setting 1.
Something like this maybe:
var values = ["option1", "option2"]; // these are the values to pre-
select
fwidget.setValue(values);
Cheers,
Robin
