Using JForm Designer I am trying to change the class of a JPanel in the properties window from JPanel to various custom classes, all of which subclass JPanel.
Sometimes it works, sometimes it fails with the message:
panel1: Can not morph non-toplevel component to non-visual bean.
What is a non-visual bean? Why are some of my subclasses recognized as visual vs. non-visual beans?
The JForm Designer documentation has been updated.
It now says explicitly that Visual Beans must inherit from java.awt.Component.
I guess that’s the all of it.
