I have a three files index.xhtml, (Managed Bean) and

My bean

The class that implements ValueChangeListener

It doesn't work ! Is this way to call setCapital() method right ?

The more complicated and more JSF-specific your code is, the more likely you're not doing it right. Consider that as the #1 rule for JSF. JSF is designed to do as much for you as possible and do it automatically.

In the case of setting the EventBean's country property, you can discard the valueChangeListener entirely. JSF will automatically invoke the EventBean's setCapital(). Provided of course, that your form does not contain any invalid data in it. When in doubt, add an "<h:messages/>" element to the page.

An IDE is no substitute for an Intelligent Developer.
I agree. Here's the link:
