Answer 1

Following code populates CN1 Multilist dynamically from a Hashtable. Here usersList is a Hashtable. Write the code in the List Model event of the List.

    Vector vec = new Vector();

    Object[] keys = usersList.keySet().toArray();

    for (int iter = 0; iter < keys.length; iter++) {
        InputStream is = null;
        Hashtable temp = new Hashtable();
        temp.put("Line1", usersList.get(keys[iter]));
        vec.addElement(temp);
    }
    cmp.setModel(new DefaultListModel(vec));
    vec.clear();

Thanks!

I don't understand the problem? Instead of using an array just pass a collection with your data or pretty much anything you want.

If you want to download data dynamically or something more elaborate just implement your own ListModel to fetch data asynchronously e.g. https://code.google.com/p/codenameone/source/browse/trunk/CodenameOne/src/com/codename1/cloud/CloudListModel.java
