To: comp.lang.java.gui I have the following code (with line numbers for convenience): //jList is a JList 1 jList.setFocusable(false); 2 jList.removeListSelectionListener(this); 3 jList.setListData(new String[0]); //Clear in case new data is empty //Other code for setting data 11 jList.setSelectedIndex(refIndex); 12 jList.setFocusable(true); 13 jList.addListSelectionListener(this); 14 componentIndex = jList.getSelectedIndex(); I've removed the class itself as the ListSelectionListener at the start (at line 2), then add it later (at line 13). While testing, I found my data was being updated more frequently than appropriate and when it was updated, it would loop through multiple times. I tracked it back, by throwing an error and printing a stack trace, to both lines 3 and 11. Both of these lines, at different times, are triggering the ListSelectionListener. Both of the offending lines are after I've removed the Listener and before I reattach it. Why are they triggering the Listener when it's not attached?
