I'm sure you can do something in a filter to break things. :) But I
don't think the nature of a filter alone will have any effect on this.
The code that is throwing an exception appears to be doing so b/c the
PartialTraversalViewRoot is not a UIComponent. I'm 99% sure this means
its (null) as it is always a UIComponent.
It could be null if the FacesContext is null. Or if the ViewRoot to be
created is created as something other than a PartialTraversalViewRoot
implementation (i.e. the normal UIViewRoot). The 2nd cause should not
happen unless you've done something to configure how JSF creates the
ViewRoot (perhaps used a framework like Ajax4JSF, or some other
framework); this is the configuration that ensure a proper ViewRoot is
created (this is done for you automatically):
<component>
<component-type>javax.faces.ViewRoot</component-type>
<component-class>com.sun.faces.extensions.avatar.components.PartialTraversalViewRootImpl</component-class>
<component-extension>
<component-family>javax.faces.ViewRoot</component-family>
</component-extension>
</component>
The ViewRoot will be null if the FacesServlet is not executed. In your
stack trace, I do not see the FacesServlet, however, I'm not sure if
there's more to it than this. I'm guessing that is your problem.
Good luck!
