Why won't my JList update?

My JList is first dimensioned to an array with 100 elements in it but then in a function i set it to null and then I set it to a different array with a smaller amount of elements. Then i call repaint() to refresh the pane but it still doesn't change anything. The JList on my pane still shows the items in the old array. How do i fix this?
