NullPointerException when adding event to Jbutton - Netbeans

[sokeefe]

I am trying to edit the GUI of a project in Netbeans. In particular, I am trying to add new JButtons. I get a NullPointerExce ption when I try to add an Event to any given JButton (even ones that already exist) in my application using the Design Editor.

I go about this by right-clicking on the JButton in the design editor, navigating to Events -> Action -> actionPerformed . The auto-generated code appears for a brief moment before it disappears and throws the NullPointerExce ption. I am using NetBeans IDE 6.1 and JDK 6u7.

Below is the details of the exception. I am in dire need of a solution, but cannot find any solutions on the web, only old Bug tickets related to similar issues that have allegedly been fixed long ago. If anyone has some ideas, please assist me!
