Hi, I have an object which I need to pass through the workflow. The object implements Serializable and I can succesfully read the object from any class which implements ActivityBehaviour. I am struggling to understand how I go about re-serializing the object so the next call to a class implement ActivityBehaviour can read the serialized object with the changes the previous class made to it? I just need someone to point me in the right direction as I'm sure I'm missing something fairly straight forward with my set up. Thanks.
