MethodBinding

[Murat Hazer <mu...@gmail.com>]

Hi,

I have a s:subform and selectOneMenu in this form, onchange i submit the
form and in the valueChangeListener method of the backing bean i am calling
another backing beans method using methodBinding and i want this method to
navigate another page (bean2.callMe excuted but it doesn't navigates or
updates the view), and #{sessionScope.code} value is not updated with the
selected items value, here is the code;

<h:form>
....
<s:subForm id="changeFORM">
  <t:selectOneMenu value="#{sessionScope.code}" valueChangeListener="#{
changer.change}" onchange="changeFORM_submit();">
    <f:selectItems value="#{changer.list}" />
    <f:converter converterId="javax.faces.Long" />
  </t:selectOneMenu>
</s:subForm>
....
</h:form>

public class Change{
....
    public void change(ValueChangeEvent valueChangeEvent) {
        facesContext.getApplication().createMethodBinding(
                    "#{bean2.callMe}", new Class[] {}).invoke(
        facesContext, new Object[] {});
    }
....
}


regards....

You are "just" calling a method.
JSF doesn't now about your navigation rules at this time.
Use the NavigationHandler for this kind of use-case

facesContext.getApplication().getNavigationHandler().handleNavigation(
			facesContext, null, outcome);


"outcome" is the string returned by #{bean2.callMe}
