I just added a new workflow container data element (populated by a method export parameter) to a workflow template in our development environment. It tests properly (method->task container->workflow container) in our development client but not in our test client (same system -- different clients). All workflow objects (to my knowledge) are client independent. Why would one client behave differently than another? Note: I've activated both the business object and the workflow template in both environments and verified that the binding is identical. (It has to be; it's the same template/version.) It's a mystery.
