Migration from 1.1.1 to nightly build

[fr...@pacbell.net]

I have an application working with myfaces 1.1.1.
I built the nightly build using maven, and the simple-example
works, but my application gets:
 
java.lang.ClassCastException

	
org.apache.myfaces.application.jsp.JspStateManagerImpl.nextViewSequence(JspS
tateManagerImpl.java:472)

	
org.apache.myfaces.application.jsp.JspStateManagerImpl.getSerializedViewFrom
ServletSession(JspStateManagerImpl.java:459)

	
org.apache.myfaces.application.jsp.JspStateManagerImpl.restoreTreeStructure(
JspStateManagerImpl.java:212)

	javax.faces.webapp.FacesServlet.service(FacesServlet.java:108)

	com.parvia.security.SessionFilter.doFilter(SessionFilter.java:91)


breakpoint in nextViewSequence:
            Map map = externalContext.getSessionMap();
            Integer sequence = (Integer)
map.get(RendererUtils.SEQUENCE_PARAM);  <--------

map.get(RendererUtils.SEQUENCE_PARAM) is a String "1"
Any idea why this is happening?
Thanks,
