Is there a way to override the names of parameters in the FlowExecutionManager (i.e. FLOW_EXECUTION_ID_PARAMETER). I don't see any setters.

The original design of our controller (before moving to webflow) called for a parameter "lt" which must exist and prevented resubmitting a form. This feature is technically obsolete with the move to Spring webflow but I am obligated to support the parameter. It would be nice if I could just set the FLOW_EXECUTE_ID_PAREMETER to "lt" and not have to worry :-) Is this possible?

Thanks
