Thanks! This worked - with the modification that you only need:
var values = new java.util.ArrayList();

I'm not sure if it's the best way, but off the top of my head...
var values = new Packages.com.java.util.ArrayList();
values.add("option 1");
values.add("option 2");
values.add(someMethodToGetAString());
values.add(someOtherMethodToGetAString());
....
fwidget.setValue(values.toArray());
Basically, the trick is to pass a simple array to the multi-value
widget containing only the values you need to set...
Cheers,
Robin
