Dear list, I am using the observer pattern in a design and would like to make both subject and observers serializable. The subject hold a base class pointer to the observes and the observers holds a base class pointer to the subject. If I have understood the library correct I must register the class for base class pointers in order to serialize the class pointer. This means that I must include the concrete subject in the concrete observers and vice versa. The means that I will run into circular dependencies. I guess that I am missing something here, the observer pattern must be frequently used and be serialized. Have anyone used the observer pattern and managed to serialize both observers and subject with pointers included. / Mikael
