Sorry. I checked that also and it seems ok. > The 'to' EL string is "#{pageFlowScope.original}". I wonder why it still checks the base type and therefore throws the exception. Is it possible to a) file a jira issue and b) create a *simple* re-produceable test-case? That makes it easier to debug the issue.
