So I got something almost working. I am not sure whether my pointcut or advice
are causing the problem. It works, but I get some weird exception after it
works :(
after(ActionEvent e) : args(e) && execution(void
java.awt.event.ActionListener+.actionPerformed(ActionEvent))
{
if(e.getActionCommand().equals("Commit"))
System.out.println("Commit clicked");
}
It prints the string only when that specific button is clicked, but then I get
some unexpected Exception, and walking through the debugger did not help me
find it. It just goes to the Please help if you have any ideas. Here is what
my output looks like from the console.
Commit clicked
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException

Subject: [aspectj-users] Aspect for clicking on a JButton
Hey all,
I am having a hard time trying to figure out how to make a pointcut that can
trigger when a JButton is clicked. Also, would I be able to target specific
buttons being clicked? What can I do?
