Refreshing listbox values

[frameexpert]

Hi, I am using ExtendScript on Windows 7. I have a listbox with data in it. I want to be able to update the listbox with a brand new array of data on the fly when the user clicks the << or >> buttons. Here is what my palette looks like:

In my button events, I have:

palette.attrValues.items = values;

where values is the new array of strings. But the palette does not update. Any advice would be appreciated. Thank you very much.

Thanks to Peter Kahrel excellent ScriptUI guide, I found out a good way to do it. I simply create a new list box, add it to the palette and delete the old one. It works great. I am using this function inside my script. It may not make total sense because you can't see the whole script, but you should be able to see where I am making a new list and deleting the old one.

function updateList () { 
    var newList; 
    palette.currIndex = set.index; 
    palette.text = "attribute: " + set.name; 
    // Create a new list for the new values. 
    // Use the existing list's bounds so the new list will be the same size/location.
    // set.values contains the new values for the listbox.
    newList = palette.listGroup.add ("listbox", palette.attrValues.bounds, set.values, {multiselect:true}); 
    newList.alignment = ['fill', 'fill']; 
    // Delete the old list.
    palette.listGroup.remove (palette.attrValues); 
    // Update the variable so it points to the new list.
    palette.attrValues = newList; 
}
