Bookings Faces sample on WebSphere v8

Has anyone had any luck getting the sample app "booking faces" (SWF + JSF) working on WebSphere v8? WebSphere uses it's own JSF implementations by default, so I removed the Sun RI dependencies. (Default is "MyFaces") Also, I commented out the security bits for now, but I get the following error:

RTFM. Solved my problem. For future reference:

http://static.springsource.org/sprin.../ch02s02.html:
Note that partial state saving is only supported with Sun Mojarra 2.0.3 or later. It is not yet supported with Apache MyFaces. This is due to the fact MyFaces was not as easy to customize with regards to how component state is stored. We will work with Apache MyFaces to provide this support. In the mean time you will need to use the javax.faces.PARTIAL_STATE_SAVING context parameter in web.xml to disable partial state saving with Apache MyFaces.

Added the following to my web.xml and it works great:
<context-param>
<param-name>javax.faces.PARTIAL_STATE_SAVING</param-name>
<param-value>false</param-value>
</context-param>
