Keeping my nodeIcon while editing and another question

Question

Hi group, I have two questions which made my life pretty unpleasant.
1. I try to edit tree nodes which contain custom Icons but at the moment as I start editing them my these vanish (Java replace them with default ones)and when I am ready with the editing they are displayed again.
I suppose I have to define my own CellEditor which extends DefaultTreeCellEditor but what I have exactly to do ???
2.The second question also concerns the editing.My problem is not managing to edit a cell again after a non valid entry has been made.The situation looks like this:
/**Adding the node to the tree*/
DefaultMutableTreeNode newNode = new DefaultMutableTreeNode("");
DefaultTreeModel model = (DefaultTreeModel)tree.getModel();
model.insertNodeInto(newNode, selectedNode,
selectedNode.getChildCount());
/**Starting editing at Path*/
TreePath treePath = new TreePath(model.getPathToRoot(newNode));
tree.startEditingAtPath(treePath);
So far so good...
Then I take the value of the editor with
String newName =(String)tree.getCellEditor().getCellEditorValue();
and then I say for example
if(newName.equals("")){
tree.startEditingAtPath(treePath)
With other words if the entry is empty start editing again but I didn't work.
If anyone can help me understand my problem better than please do make your contributions I would appreciate that much.
I thank you in advance

Hi,
I have a similar problem as urs. if u have found a solution cud u please help me out.
This is how I set my editor
ESMOPTreeCellEditor oTreeCellEditor = new ESMOPTreeCellEditor(m_tree, oOPTextField);
m_tree.setCellEditor(new DefaultTreeCellEditor(m_tree, orenderer, oTreeCellEditor));
And Tree cell editor defeined below
private class ESMOPTreeCellEditor extends DefaultCellEditor implements CellEditorListener
public ESMOPTreeCellEditor(JTree p_oTree, ESMTextField p_oTxtField)
public boolean isCellEditable(EventObject oEvent)
public Component getTreeCellEditorComponent(JTree tree,Object value, boolean isSelected, boolean expanded, boolean leaf,int row)
public void editingCanceled(ChangeEvent e)
public void fireEditingStopped()
public void editingStopped(ChangeEvent e)
Now I have a tree cell rendere defined and I have overridden these methods
public Icon getLeafIcon(){}
public Icon getClosedIcon(){}
public Icon getOpenIcon(){} to return the icon which i display in my renderer. This way I am able to get the right icon even in edit mode, but my rendereing needs to display an Icon with a background color which i am loosing presently. I know this may not be a right way to show the rendering in edit mode.
Thanx,Anu
