Hi, I don't understand why ParameterPropertyWorker makes parameter mutator throw an exception if called over an unbounded parameter. I see this behaviour as illogic: ParameterPropertyWorker do create a property field so why not using this field to set the parameter if no binding is available instead of throwing an exception? As a possible useful example the field might be changed by a listener and later reused later on during rendering.
So in my opinion if there's no binding there should be no exception thrown and obviously setObject should not be called on the (null) binding, this would be the correct behaviour. But maybe it's just my misunderstanding of tapestry logic and there's a very good reason to throw this exception.
