Java Swing Listeners: components that listen to each other

Question

I want to write two JList (categories and elements). When I click on one category, it should select all the elements for this category, and when I click on one element, it should select its categories. So the JList will be a ListSelectionListener listening on each other and changing the selection.

Should I be wary of some kind of "cycle "Is there a way to say that the event was destroyed? How do people deal with this situation?
