Duplication problems

[Casen Densmore]

I am having the problem of an actionListener duplicating, or perhaps an error in my code. When ther user clicks the arrow_left1 button it move nodes from one tree into the another. When they click the save1 button it saves the current information. The problem comes when I try moving stuff over after I have saved the information. For some reason it duplicates itself. The first time I click save it duplicates once, the second time...twice etc....

relevant code is below....
//if save button is pressed
save1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent event) {

 arrow_left1.addActionListener(new java.awt.event.ActionListener() {
            public void actionPerformed(java.awt.event.ActionEvent event) {
             DefaultMutableTreeNode node = (DefaultMutableTreeNode)
                     Release_jTree2.getLastSelectedPathComponent();
            System.out.println("got here");
            int count = 0;
            if(node == null)
              return;
            DefaultMutableTreeNode new_node = new DefaultMutableTreeNode(node.toString());
          
                        for (Enumeration e = root1.depthFirstEnumeration()  ; e.hasMoreElements()  :wink:  
                    {
                      if(new_node.toString().equals(e.nextElement().toString()))
                      {
                                               count ++;
                        JOptionPane.showMessageDialog(null, new_node.toString().substring(2) + " has already been added.", "Error", JOptionPane.ERROR_MESSAGE);
                           return;
                      }
                    }
                
                if(node.isLeaf()){
                  tree1.insertNodeInto(new_node, root1, root1.getChildCount()-1);
                }
                
                else
                {
                  
                for(int x = 0; x < node.getLeafCount(); x++){
                   new_node.add(new DefaultMutableTreeNode(node.getChildAt(x).toString()));
                                    
                }
                tree1.insertNodeInto(new_node, root1, 0);
                }
                for(int x = 0; x < root1.getChildCount(); x++)
               {
               
                  for(int y = 0; y < root1.getChildAt(x).getChildCount(); y++)
                  {
                    for(int z = 0; z < root1.getChildCount(); z++)
                    {
                      if(root1.getChildAt(z).toString().equals(root1.getChildAt(x).getChildAt(y).toString())){
                        JOptionPane.showMessageDialog(null, root1.getChildAt(z).toString().substring(2) + " has been removed because the " + root1.getChildAt(x).toString().substring(2) + " folder already contains the entry.", "Notice", JOptionPane.ERROR_MESSAGE);
                        tree1.removeNodeFromParent((MutableTreeNode)root1.getChildAt(z));
                      }
                    }
                  }
                }
                
                Release_jTree1.expandPath(new TreePath(root1.getPath()));
               
                
                
  
            }
        });  

Output:
got here
got here

On one click of arrow_left1 after saving got here is printed out twice... Any reason why it would be doing that?

Ya....it was just bad programming.....
