Monkeyden,
See [1]. This is from the front page of the wiki.
Alternatively, all managed beans can be accessed directly from the
appropriate scope (i.e. request, session).
I found the following utility method (based on the wiki page) useful in
my application:
/**
* Look up a managed bean by JSP-EL value-binding expression
* @param ref a value-binding expression to lookup
* @return the managed bean referenced by the expression
*/
public static Object getManagedBean(String ref) {
// Find or create the web-tier data object
// ref like "#{myBean}"
FacesContext context = FacesContext.getCurrentInstance();
ValueBinding binding = context.getApplication().createValueBinding(ref);
return binding.getValue(context);
}

Im using a Tomahawk tabbedPane in my JSP

I want to implement a TabChangeListener, to set the "selectedTab" value of
the backing bean. I don't need to change the view of the component at all,
since that's handled automatically. I just need to know what the currently
selected tab is. Looking at the hierarchy, there doesn't seem to be a way
to get my backing bean instance from session to set the value. This is how
I would expect this to be done. Please tell me if I'm way off base or not.
processTabChange(TabChangeEvent tabChangeEvent){
MyBackingBean myBean = [get the bean somehow];
myBean.setSelectedTab(tabChangeEvent.getNewTabIndex());
}
