JPanel, jScrollPane, jLists and removing components

Question

I have a method that when a textfield gets the focus, I want my jScrollPane to clear out. I don't want to removeAll, but I only want to remove the 2 jLists: listCheckBox and listDescription.
What I have below doesn't visually remove my jLists.
What can I do?
jScrollPane1.remove(listCheckBox);
jScrollPane1.remove(listDescription);
jPanel1.revalidate();
jPanel1.repaint();

Answer 1

This is the entire code. It should compile. I don't know if this counts as a SSCCE or not. I am using the JDK 1.5 & Swing Layout Extensions 1.0 libraries. With this code, I have my jScrollPane to clear out correctly. Now, the mouselistener only works every other time the find button is clicked.
