GUI Designer: catch exceptions not only on loading component class, but also on painting it

Created: 30 Sep 06 22:28   Updated: 28 Sep 07 16:48
Component/s: GUI Designer
Fix Version/s: Diana Final

Original Estimate: Unknown Remaining Estimate: Unknown Time Spent: Unknown

Build: 5,757


 Description  « Hide
GUI Designer. Create a custom component A that use another class B (invokes static method of that class in my case). Compile. Put component on GUI form. Close form.
Delete B.class file. Try to reopen form. UI hangs up during this action, the eternal chain of NoClassDefFoundErrors is in console.
(Notice, that deleting A.class file is processed correctly: no hang up + error message.)

The common problem is that UI Designer check classes availability on loading component's class, but does not check their availability on painting them. Another case to reproduce: custom component: 
import java.awt.Graphics;
import javax.swing.JButton;

public class JButtonSurprise extends JButton {
	public JButtonSurprise() {
		super();
	}

	public void paint(Graphics g) {
		super.paint(g);
		Object o = null;
		o.toString();
	}
}

and exception, started with:

{format}
java.lang.NullPointerException
