JSF Portlet default view (FacesPortlet)

Question

If we are creating a JSF based portlet using Sun's JSF RI and jsf-portlet bridge, then in portlet.xml we define this:
{color:#0000ff}
<portlet>
<portlet-name>myPortlet</portlet-name>
<portlet-class>
com.sun.faces.portlet.FacesPortlet
</portlet-class>
<init-param>
<name>com.sun.faces.portlet.INIT_VIEW</name>
<value>/default.jsp</value>
</init-param>
</portlet>{color}
But in faces-config.xml, we define our navigation using navigation-cases, like this:
{color:#008000}
<!-- Global Error -->{color}
{color:#0000ff}
<navigation-rule>
<navigation-case>
<from-outcome>exceptionNavigation</from-outcome>
<to-view-id>/error.jsp</to-view-id>
</navigation-case>
</navigation-rule>{color}
What I'm trying to do is this:
I want to programmatically access the navigation rule which references the default view.
I can fish out the INIT_VIEW value using:
{color:#0000ff}
String initView = application.getInitParameter(com.sun.faces.portlet.LifecycleImpl.INIT_VIEW_PARAMETER);{color}
But this returns me the actual jsp name, ie: {color:#0000ff}/default.jsp{color}
This means I cannot use faces to navigate to it, like this:
{color:#0000ff}
application.getNavigationHandler()
.handleNavigation( context, null, initView );{color}
As the navigation model is core to JSF, would it not be better for FacesPortlet to require, in portlet.xml,
a global navigation-case rather than just a jsp page?
This would apply to EDIT_VIEW, HELP_VIEW, etc.
In order to implement the functionality I want, I have to specify my default or INIT_VIEW page twice, once in portlet.xml and a second time in faces-config.xml. What is more, I cannot use this as independent code, because I have to know or prescribe the navigation-case containing the default/initView to the user of the code:
{color:#0000ff}
<navigation-case>
<from-outcome>com.sun.faces.portlet.INIT_VIEW</from-outcome>
<to-view-id>/default.jsp</to-view-id>
</navigation-case>{color}

Answer 1

I have answered my own question. This is how to programmatically access the INIT_VIEW jsp in this situation:
ExternalContext econtext = context.getExternalContext();
String initViewId = (String) econtext.getRequestMap().get(
(String) econtext.getRequestMap().get(
com.sun.faces.portlet.LifecycleImpl.INIT_PARAMETER ));
UIViewRoot viewRoot = context.getApplication().getViewHandler().createView(context, initViewId);
context.setViewRoot(viewRoot);
context.renderResponse();
It the viewId IS the jsp name, and navigation can be achieved directly on the jsp name using the ViewHandler class. This is what the NavigationHandler does, under the bonnet (sorry, hood).
