Hi,
I'm wondering what's the correct way to call a
method in the backing bean from a JSF page. What I tried is to
use , the backing
bean method returns an empty string, so nothing gets printed out in the page.
Which works, but I am not sure this is the correct way to do it.
thanks,
Saul
Try h:commandLink or h:commandButton.
If your method returns a string that doesn't match any navigation-rule
in your faces-confix.xml then the same page you came from will be
rendered again.

The value attribute should be a *value* binding expression. It must
bind to a *property*. So you do something like this ...
value=#{theBackingBean.foo}"
and in your backing bean you have
public String getFoo()
{ ... }
public void setFoo(String fooValue)
{ ... }

Thanks for your response. I guess I didn't make me clear here. My question
is how to call a method in the backing bean from a JSF page without
rendering out anything to the screen.

Hi,
i think you are looking for somthing like a PhaseListener.
You can configure such a Listener in faces.xml.
make your listener to return javax.faces.event.PhaseId.RENDER_RESPONSE
in getPhaseId() method and the beforePhase() method of your listener
is invoked just before rendering.
