Confused about View ID

[James Reynolds <Ja...@intermountainmail.org>]

I have a page that lists Contracts. On this page is a booleanCheckBox
that filters the list based on a certain criteria.  Here is the
ValueChangeListener I'm using:

public void compOnlyChecked(ValueChangeEvent vce) {
        compOnly = (Boolean) vce.getNewValue(); //compOnly is a boolean
property in the managed-bean
        getFacesContext().renderResponse();
    }

So far, it works fine.  However, if I click on one of the contracts
(which navigates to the detail page), then click the back button to
return to the list, then click the booleanCheckBox, the *detail* page is
the one that is restored.

I suspect that the solution to this is to set the view ID to the
Contract View page inside of the ValueChangeEvent, but my efforts are
throwing Evaluation Execptions (stack trace below).  This is how I
modified the Value Change Listener, which is obviously incorrect.

public void compOnlyChecked(ValueChangeEvent vce) {
        compOnly = (Boolean) vce.getNewValue();
	  getFacesContext().getViewRoot().setId("/contractList.jsf");
        getFacesContext().renderResponse();
    }

Could you point me in the right direction?

Thanks
