this doesn't seem right... what will _ptr be set to?

[nweiz, 2011/10/24 19:48:28]

It shouldn't need to be set to anything. We override all the methods that use
_ptr to return default values. The reason we're extending is so we don't have to
generate all the get/set methods, which ultimately call {get,set}PropertyValue
anyway.
