JTreeTable: can't get CellEditor for non-tree cells to work

Question

Hi!
I'm using a JTreeTable ( http://java.sun.com/products/jfc/tsc/articles/treetable2/index.html ) in my application. In the table cells I use ImageIcons to visualize some object data. Now I need some interaction when the user clicks on these icons, but I'm not able to get any kind of cell editor to work with the table's cells.
I now play around with the TreeTable 2 example code and it's about the same. I can't even get a JTextField to work as an editor. I've been searching this forum and the web but did not find an appropriate solution or sample code.
Is someone out there who can help me out?

Hi there.
Hopefully we can help each other out as I am also struggling with the example from sun.
I have managed to get an editor to work but I'm using a check box.
Very simple, I took all the code from sun. In the TreeTableModelAdapter, I put code for isCellEditable() and for setValueAt(), like this
public boolean isCellEditable(int row, int column) {
         if(column ==0){        
              return treeTableModel.isCellEditable(nodeForRow(row), column);
         else if(column == 1){        
              return true;
         else return false;          
    public void setValueAt(Object value, int row, int column) {
          if(column ==0){
               treeTableModel.setValueAt(value, nodeForRow(row), column);
          else if(column == 1){
               DefaultMutableTreeNode theNode = (DefaultMutableTreeNode)nodeForRow(row);
               NewsNode theNewsNode = (NewsNode)theNode.getUserObject();
               if(!theNewsNode.isSelectable()) return;
               Boolean theValue = (Boolean)value;               
               theNewsNode.setSelected(theValue.booleanValue());
             fireTableChanged(null);
    }I'm not sure if that's what you need but it worked for me.
Maybe you could elaborate further.
Cheers,
