Determining the current viewId

Question

Hi, I need to determine the current view id, therefore I am using the following code:
/* adf-settings.xml */
<adf-settings xmlns="http://xmlns.oracle.com/adf/settings">
  <adfc-controller-config xmlns="http://xmlns.oracle.com/adf/controller/config">
    <lifecycle>
      <phase-listener>
        <listener-id>myPagePhaseListener</listener-id>
        <class>obasi.common.domain.myPagePhaseListener</class>
      </phase-listener>
    </lifecycle>
  </adfc-controller-config>
</adf-settings>
/* myPagePhaseListener */
    public void beforePhase(PagePhaseEvent pagePhaseEvent) {           
        try {           
            if (pagePhaseEvent.getPhaseId() == Lifecycle.PREPARE_MODEL_ID) {
                for (Object child:FacesContext.getCurrentInstance().getViewRoot().getChildren())
                    if (child instanceof RichDocument)
                        System.out.println(FacesContext.getCurrentInstance().getViewRoot().getViewId());
        } catch (Exception ex)
            // ignore
    }But this doesn't seem to work accurately. Some viewId's are only "detected" after leaving a page...
I noticed that this happens when the URL inside my browser also remains pointing to the previous page.
Is there a way to solve this?
Thanks in advance,
Charles.

Hi,
Thanks for helping me out, Simon.
I am not sure about what changes should be made to my web.xml in order to not have the resources as view id's.
So here goes my web.xml - in the hope that you would be so kind to point me out where the problem lies.
<?xml version = '1.0' encoding = 'windows-1252'?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5" xmlns="http://java.sun.com/xml/ns/javaee">

        <description>If this parameter is true, there will be an automatic check of the modification date of your JSPs, and saved state will be discarded when JSP's change. It will also automatically check if your skinning css files have changed without you having to restart the server. This makes development easier, but adds overhead. For this reason this parameter should be set to false when your application is deployed.</description>
