[Eap-list] #601: NPE when creating method from unknown reference

[Brian Majewski]

javax.swing.JPanel panel = new JPanel();

panel.add( createSubPanel() );

 

The lightbulb came on, and it suggested a method named "add". Accepting this, caused the following NPE.

 

Tried again a moment later by editing the unknown reference to be createSubPanel2(). The lightbulb came on again, suggested a properly named method, and created it as expected.
