Hi there,
    I'm working on an applet and trying to understand the JList class.
So far I understand that you simply pass as array of strings to its
constructor in order to populate it, but that only seems to work once!
Here is a method I created for populating a JList:

String WordList[];

void populateListBox()
{
         WordList = WDS.getNewWordList(10,6);
          jList1.setListData(WordList);
}

WDS.getNewWordList(10,6) is a class method that returns a string array
of a list of randomly selected words derived from a Vector holding all
the words found in a dictionary.

When this is run the first time, it works fine.  However, ever
subsequent call to this method doesn't result in the JList repopulating
with a new set of words.  It just continues to display the first set of
words, and that's it.

What do I need to do to make the listbox do what I expect it to do?  I
want it to repopulate with a new set of words everytime I call this
method!
