Description worndown 2005-12-25 07:51:41 UTC 
Here's how to reproduce it in NetBeans 5.0 beta 2:

1. Create JFrame.
2. Add JTree (this adds JScrollPane as well).
3. Select JScrollPane and click at "viewport" button in properties.
4. Press OK in opened dialog. When dialog is closed, JTree control will not 
show tree anymore.
5. Now click on the JTree control and you will get exception.

See attached screen shots and log.

Reassigning to "form" for evaluation.
Comment 6 Tomas Pavek 2006-01-02 11:45:41 UTC 
This way the viewport of the scroll pane is accidentally set to null which
causes the problems.

Perhaps we should not expose 'viewport' property at all - it can't be handled
reasonably as a property becasue it affects the component/container hierarchy. I
don't think changing viewport of JScrollPane is a common task done in GUI
builder - if you really need it, set it e.g. via user code (post-creation code).
