I have a JSplitPane with a JTree on the left and a JTabbedPane on the
right. I want the JTabbedPane replaced, based on the actual type of the
object that is clcked.

That works OK but the following happens:

On the first time click on an object in the tree, the JTabbedPane
appears but only half filled. The second time I click (without changing
the object in the tree), the JTabbedPane appears fully filled.

Exactly the same code is executed:

if(e.getClickCount() == 1)
{
DefaultMutableTreeNode selectedObject =
(DefaultMutableTreeNode)selPath.getLastPathComponent();

if( selectedObject.getUserObject() instanceof RootNode)
{
  RootTabbedPane tabbedPane = new RootTabbedPane();
  splitPane.setRightComponent(tabedPane }
else if( selectedObject.getUserObject() instanceof IntermediateNode)
{
  IntermediateTabbedPane tabbedPane = new IntermediateTabbedPane();
  splitPane.setRightComponent(tabedPane }
}

Can anyone give me an idea on how to solve this problem?

TIA
