Hello, I hadn't used referenceproperty much before in my applications, but have cause to use it now, and the behaviour of it is really confusing me.
I have an entity with a reference to a second entity. >From the documentation I believe I should be able to say something like: x.entityb_set to retrieve all instances of model entityb that reference x. This works, but as soon as I do an appcfg.py update of my application, it stops working. It's like for the existing data, the application has forgotten the references. I get the error: AttributeError: 'ModelA' object has no attribute 'modelb_set' (I have replaced the model names here) If I delete the data in my datastore and recreate these entities, it works. Until I do another update, when again I get this error. Why would it behave like this? It's frustrating me no end. If it makes a difference, these models are extending from search.SearchableModel.
