Notes

Scoped Variables often return an ArrayList Object, which is a problem when you want to store the values easily enough into a NotesDocument Field.

This function allows the converting of an ArrayList to a Vector. In most cases this function can be used without modifications, although in some cases you might not using a String Object in the ArrayList or Vector.

e.g. If you want to return a value from a viewScope Variable (Holding an array of values from a Control) and save it into a NotesDocument:

doc.replaceItemValue("MultiValueField", TranslateArrayListToVector(viewScope.get("Values"));

UPDATE: Thanks to "Martin Rolph", "Jesse Gallagher", a simpler alternative to achieving this without having to apply my Snippet is the following:

doc.replaceItemValue("MultiValueField", new Vector(viewScope.get("Values")));

@SuppressWarnings("finally")
public static Vector<String> TranslateArrayListToVector(ArrayList<String> tempArray) {
	Vector<String> newArray = new Vector<String>();
	
	try {		
		for(String temp : tempArray) {
			newArray.add(temp);
		}
	} catch (Exception e) {
		e.printStackTrace();
	}finally {
		return newArray;
	}
}

Another way is by using collections, w

Collections.copy(vector,arrayList);

I think you can just do

doc.replaceItemValue("MultiValueField", new Vector(viewScope.get("Values")));

as a collection will accept another collection in the constructor
