Please make VariableMap or VariableScope instance of java.util.Map! At least methods put(Object, Object) | get(Object) | containsKey(Object) should be implemented. It is a problem to use it inside Wicket (put, get) or MVEL (put, get, containsKey), because they need this methods to bind variables. That's why I need wrappers what I don't like (or I need to touch our code what I don't like even much more). Thanks for good workflow engine!
