Gary Brown commented on RTGOV-522:
----------------------------------

Hi Ivan

Thanks for finding the original problem. In RTGov 1.0 the context type had a default value of 'Conversation' - so in these cases the json serialized representing didn't include the type field for any Context object with type=Conversation.

Although this reduced the size of the serialized representation (as it didn't include unnecessary default values), the json representation wasn't as clear. Therefore it was changed to remove the default value - so the sample data needs to be updated to explicitly include the conversation type.

The initial npe also needs a guard, as if RTGov 2 is reading json serialized data produced by RTGov 1, then it may still find a null type.
