Does not show the child

Question

I have two trees (tree1 and tree2).I am trying to copy the children of tree1 to tree2. When I display tree2, it shows only the root and not it's children. What might be the problem?
Thanks.

See code below.tree1 is displaying fine.
private void initTreeCustomer() {
     //treeRootNodeCustomer_ = new EuamDefaultMutableTreeNode();
     treeRootNodeCustomer_ = (EuamDefaultMutableTreeNode)treeRootNode_.clone();
     initTreeObjectCustomer();
     treeScrollPaneCustomer_ = new JScrollPane( jTreeCustomer_ );
     treePanelCustomer_.add(treeScrollPaneCustomer_, BorderLayout.CENTER );
     treePanelCustomer_.setVisible(false);
private void initTreeObjectCustomer() {
          //Initialize 'Customer' View Tree Object
     if( jTreeCustomer_ == null ) {      
     jTreeCustomer_ = new JTree( treeRootNodeCustomer_ );
     jTreeCustomer_.setCellRenderer( new EuamTreeCellRenderer());
private void showCustomerView() {
          DefaultTreeModel treeModel = (DefaultTreeModel)jTreeCustomer_.getModel();
     for (int i=0;i<treeRootNode_.getChildCount();i++) {
     EuamDefaultMutableTreeNode node = (EuamDefaultMutableTreeNode)((EuamDefaultMutableTreeNode)treeRootNode_.getChildAt(i));
          if(node != null) {
treeModel.insertNodeInto (node,treeRootNodeCustomer_,treeRootNodeCustomer_.getChildCount());
          //treeRootNodeCustomer_.add(node);
}

I forgot.Later I do -
treePanelCustomer_.setVisible(true);
The root is shown but not its children.
