Hi! Thanks for response - you're right, one of he equals methods are invalid (always returned false). Why should be my solution complicated - these classes are hibernate pojos!

Did you test your converter to check if your home-grown serialization and equals/hashCode really works? An expression like the following should always return true for your converter to work properly: person.equals(getAsObject(getAsString(person))) Your solution seems to be quite complicated but on the other hand I don't know "how equal" your object must be (maybe it is enough to use the id of the person?). regards Michael
