getBeans called within renderComponent within AbstractFormCompone nt subclass

[Ro...@anitefinance.com]

I have copied the Submit component with the intention of providing some
modified functionality.

Within the "renderComponent" method of the "Submit.java" is the following
code snipit

....
IActionListener listener = getListener();
            
if (listener != null)
listener.actionTriggered(this, cycle);
....

To cut a long story short  I have replaced the above code with a call to
"getBeans". However this is returning me an empty collection. 

However if I re-instate the listener then calls to "getBeans" within the
listener method return all the beans I expect.

My design for this component relies on having access to the beans within the
page or other enclosing component. 

Any ideas or explanations would be most gratefully received.


Thanks

Do you define any beans in your CustomSubmit component?

Perhaps you want to invoke getContainer().getBeans().

Why don't you create a bean that implements IActionListener and just set that as the listener for
the existing Submit component?
