Generating a multicast event, through the "beans pattern" node in the Projects  
tab, does not work if the Listener interface contains non-object signatures.  
  
Example (does not work):  
interface MyListener extends EventListener {  
   public void actionPerformed(boolean on_off); 
};  
 
Similar example (that works): 
interface MyListener extends EventListener { 
   public void actionPerformed(Boolean on_off); 
}; 
 
However, per section 6.4.1 "Event methods with arbitrary argument lists" from 
the Java Beans spec, this should work. 
 
Most dramatically, NetBeans does give no feedback about what it did or did not 
do. If it is a limitation that is not worth implementing, at least a feedback 
should tell the user that it did not generate the code for some reason.
