I have a Store configured with a JsonReader, a JsonWriter and a DirectProxy. I have set a directFn for the DirectProxy.
When the Store is loaded, the Function is called without any Parameters and returns data that is imported into the Store by the JsonReader, no Problem.
When the store is updated, the function is again called, again without any parameters.
What is the recommended technique to determine on the server side what kind of operation has been performed on the Store?
