Problems JList and DefaultListModel

Question

Hi!
I've got a problem with the removing of items from a DefaultListModel.
Assume this:
public class ImageList extends JList implements DropTargetListener {
private DefaultListModel dlm = new DefaultListModel();
public void setListData(ArrayList al) {
for(...) {
//do some stuff here
dlm.addElement(al.get(i));
this.setModel(dlm);
}In the main Frameclass are an instance of ImageList and a JButton for deleting a selected item from the list.
content of the actionPerfomed-method of JButton:
DefaultListModel model = (DefaultListModel)customContentPane.imageList.getModel();
int index = customContentPane.imageList.getSelectedIndex();
if(index!=-1) {
imageData.remove(index);
model.remove(index);
}I'm developing with JBuilder and JDK 1.3.0_02 and there the removing works fine!
But with JDK 1.4.1-rc-b19 i'm getting an ArrayIndexOutOfBoundsException when i try to delete the last item. The exceptions says index: 0, size: 0!
But same code works without any problem with 1.3!!
Does anybody knows a solution?
Thanks in advance
Martin

Answer 1

Its me again!
After some debugging i found out, the IndexOutOfBoundsException always gives 'Index: -1' back, although an item IS selected!
And the imageList.getSelectedIndex() returns the true current selected item and not -1.
Is it a bug in the JList and the DefaultListModel?
