SWF JSF2 Bound UI Components loosing state

When using a UI component value binding such as

<h:inputText binding="#{facesRequestScopedBean.component}" />

the state is lost when a validation error occurs for another input on the same form.

Note we are using a JSF managed request scoped bean as the component tree can't be serialised and stored in a flow bean. Even though the bean is request scoped, SWF is creating new instances within the lifecycle of a single request.

This could be related to JsfView.getUserEventState() returning null instead of the ViewRoot when JSF2 is in use.

This could be considered a limitation of combining SWF with JSF2 rather than a bug but I haven't come across any mention of this problem on the forums or Jira.
