Hi,

I have developed a test program to work with JTree. I have a very simple 
gui-structure that looks like:

This
     contentPane(BorderLayout)
         statusBar
         jToolBar
         jSplitPane1
             currentSelectionField
             jScrollPane1
                 tree

All by a sudden, while swapping between Source and Design tabs - the 
design window turns red and I get the following message:

Failed to create live value from JPanel contentPane;: null
Failed to create live visual subcomponent contentPane (BorderLayout) as 
javax.swing.JPanel; creating a red component in its place
Failed to create live value from JTree tree;: null
Failed to create live visual subcomponent tree as javax.swing.JTree; 
creating a red component in its place

I have no idea what to change or even where to look for an error. The 
program runs fine and I have tried to alter the size, preferred and 
minimum size everywhere - but nothing works.

I'm running JBuilder 2005 Foundation
