Allow clear selection in SourceList

[GoogleCodeExporter]

Hello!

I would need a way to deselect an item in SourceList. I tried with 
sourceList.setSelectedItem(null) but an exception occurred:

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: The 
given item is not part of this model.
    at com.explodingpixels.macwidgets.SourceListModel.validateItemIsInModel(SourceListModel.java:225)
    at com.explodingpixels.macwidgets.SourceList.setSelectedItem(SourceList.java:204)
        ....
    at jcodecollector.gui.MainFrame.clearSelection(MainFrame.java:245)
        .....

Suggestion (?):

public void setSelectedItem(SourceListItem item) {
  if (item == null) {
      fTree.clearSelection();
  }
   ...
   ...

Is it correct? I'm not able to compile the entire project manually...

Meanwhile I wrote this method to workaround the problem but I'm not satisfied 
because the user sees the item disappear for a 
moment:

    private void clearSelection() {
        SourceListItem selectedItem = sourceList.getSelectedItem();
        SourceListCategory parent = null;
        Iterator<SourceListCategory> iterator = sourceList.getModel().getCategories().iterator();

        int i = 0; // selected item position
        while (iterator.hasNext()) {
            SourceListCategory sourceListCategory = iterator.next();
            Iterator<SourceListItem> innerIterator = sourceListCategory.getItems().iterator();

            while (innerIterator.hasNext()) {
                SourceListItem item = innerIterator.next();
                if (item.getText().equals(selectedItem.getText())) {
                    parent = sourceListCategory;
                    break;
                }

                i++;
            }

            if (parent != null) {
                break;
            } else {
                i = 0;
            }
        }

        // remove and re-add in the previous position
        sourceList.getModel().removeItemFromCategory(selectedItem, parent);
        sourceList.getModel().addItemToCategory(selectedItem, parent, i);
    }

Thank you for your attention

jar, let me know (
