Help on FBean

Question

Hi,
Can some one help me on FBean. I'm trying to use FBean.Invoke to invoke the constructor which takes an item number as an argument and displays an image on the bean area of the form. If I hardcode the item number and use the implementation class property and specify the class name there the image comes up fine. But if I try to invoke with the FBean invoke method by passing the method name(which is constructor here), and the item number then it does not bring any image on the bean area of the form. So, can any one tell me how to use the fbean.invoke.
Thanks in advance.

Duncan,
Thanks for replying.
The reason I am trying to use FBean is that in a previous post Frank Nimphius mentioned that I should try FBean to get around a clipping problem I was having. This fixed the clipping problem, but in Forms 6 I was using VBean for communications which no longer works, I am now trying to replicate JavaBean/Form communications without using VBean with FBean.
I have now got a sample bit of code which extends Canvas with nothing visible on the canvas to firePropertyChange() which is picked up by the Form with CUSTOM-EVENT trigger. This is fine, but if I now go to my code with a JPanel the firePropertyChange() method either doesn't get fired or the Form doesn't pick this up.
The code I am using is as follows:
public class EverySecondTimer extends JPanel implements Serializable {
String str = "DATA";
Timer timer;
public EverySecondTimer() {
setSize(60, 40);
     timer = new Timer();
     timer.schedule(new RemindTask(), 0, 1 * 1000);
class RemindTask extends TimerTask {
public void run() {
java.awt.Toolkit.getDefaultToolkit().beep();
firePropertyChange(str, "true", "false");
Like I said earlier this works if it extends Canvas, extending JPanel it doesn't.
Any ideas?
Is this the correct way to fire an event in a JavaBean for a Form to react to?
Any help would be most appreciated as I am struggling with this and finding any examples that don't use VBean is quite difficult.
Thanks in advance.
