No Help it seems
So what I did is, I have overridden the ActionServlet, and in the init method instead of readint the ActionForward's from the struts-config.xml I am reading the Step Id from the workflow specific xml(configuration file). Then from the Step Id I get the view mapping for that step from a properties file. Prepare ActionForward objects and associate them to the respective ActionMapping objects.
