Here is a simple fix.
https://jsf-extensions.dev.java.net/issues/show_bug.cgi?id=36
Issue: 36
This issue makes PartialTraversalViewRoot an interface with three methods:
void encodePartialResponseBegin(FacesContext context) throws IOException;
void encodePartialResponseEnd(FacesContext context) throws IOException;
void postExecuteCleanup(FacesContext context);
It renames the old PartialTraversalViewRoot to be
PartialTraversalViewRootImpl, which implements this interface. All
non-private accesses to the class now go through the interface. The
implementation of PartialTraversalViewRoot is accessed via a new
property on AsyncResponse.
External frameworks that override UIViewRoot and wish to use DynaFaces
should declare a phaseListener that installs a PartialTraversalViewRoot
implementation in this property on the afterPhase method for the
RestoreView phase and also ensures that the viewRoot returned from the
FacesContext adheres to the partial traversal contract.
Of course, the UIViewRoot override must adhere to the rest of the
partial contract.
SECTION: Changes
M run-time/avatar/src/main/java/com/sun/faces/extensions/avatar/lifecycle/PartialTraversalLifecycle.java
- Make this class use the new PartialTraversalViewRoot interface and
getter on AsyncResponse, instead of using FacesContext.setViewRoot().
M run-time/avatar/src/main/java/com/sun/faces/extensions/avatar/lifecycle/AsyncResponse.java
- Add new JavaBeans property partialTraversalViewRoot of type
PartialTraversalViewRoot.
A run-time/avatar/src/main/java/com/sun/faces/extensions/avatar/components/PartialTraversalViewRootImpl.java
- This is the renamed class that was PartialTraversalViewRoot
M run-time/avatar/src/main/java/com/sun/faces/extensions/avatar/components/PartialTraversalViewRoot.java
- Turn this into an interface.

*
- * <p>Request Processing Lifecycle Operation</p>
- *
- * <p>On initial request, this instance behaves effectively like the
- * <code>UIViewRoot</code> from which it extends, delegating all
- * behavior to the superclass.</p>
- *
- * <p>On postback, the {_at_link #processDecodes}, {_at_link
- * #processValidators}, and {_at_link #processUpdates} methods have special
- * behaviour. If {_at_link
- * com.sun.faces.extensions.avatar.lifecycle.AsyncResponse#isAjaxRequest}
- * returns <code>false</code>, the superclass implementation of the
- * respective method is called. Otherwise, {_at_link
- * com.sun.faces.extensions.avatar.lifecycle.AsyncResponse#getExecuteSubtrees}
- * is called. This returns a list of client ids suitable for the
- * <code>execute</code> portion of the request processing lifecycle. If
- * the list is empty, call through to the superclass implementation of
- * the respective method. Otherwise, for each client id in the list,
- * using <code>invokeOnComponent</code>, call the respective
- * <code>process*</code> method on the component with that clientId.
- * After all the client ids in the list have been handled for the
- * current phase, reflectively call <code>broadcastEvents()</code> on
- * the superclass passing the current <code>PhaseId</code>.</p>
- *
- * <p>On postback, the {_at_link #encodeAll} method has special behavior.
- * If {_at_link
- * com.sun.faces.extensions.avatar.lifecycle.AsyncResponse#isAjaxRequest}
- * returns <code>false</code>, the superclass <code>encodeAll</code> is
- * called. Otherwise, {_at_link
- * com.sun.faces.extensions.avatar.lifecycle.AsyncResponse#getRenderSubtrees}
- * is called. This returns a list of client ids suitable for the {_at_link
- * javax.faces.lifecycle.Lifecycle#render} portion of the request
- * processing lifecycle. If the list is empty, call through to the
- * superclass implementation of <code>encodeAll</code>. Otherwise, for
- * each client id in the list, using {_at_link
- * javax.faces.component.UIComponent#invokeOnComponent}, call the
- * <code>encodeAll</code> method on the component with that clientId.
- * If the list of subtrees to render for this request is non-empty, set
- * the response content-type and headers approriately for XML, and wrap
- * the rendered output from the components in the list as in the
- * following example.</p>
- *
-<pre><code>
-<partial-response>
- <components>
- <render id="form:table"/>
- <markup><![CDATA[
- Rendered content from component
- ]]></markup>
- <messages>
- <message>The messages element is optional. If present,
- it is a list of FacesMessage.getSummary() output
- </message>
- </messages>
- </render>
- <!-- repeat for the appropriate number of components -->
- </components>
- <state><![CDATA[state information for this view ]]></state>
-</partial-response>
-</code></pre>
- *
- * if the <code>isRenderXML</code> value is <code>false</code>, assume
- * the renderers are handling the content-type, header, and component
- * encapsulation details and write nothing to the response.</p>
- *
- * <p>See {_at_link
- * com.sun.faces.extensions.avatar.lifecycle.PartialTraversalLifecycle} for
- * additional information about how this class helps
- * <code>PartialTraversalViewRoot</code> get its job done.</p>
- *
- * <p>This class extends <code>UIViewRootCopy</code>, which is a local copy
- * of <code>UIViewRoot</code> that makes the <code>broadcastEvents</code> method
- * public. This is necessary to allow easily broadcasting events during the
- * AJAX lifecycle.</p>
