I have an app which is fetching data from Lookback API. I get User ObjectID in the data, however I would like to get the DisplayName of the User instead of ObjectID. I tried using store to get the user DisplayName with ObjectID filter, but I don't get the name of the user, until I finish my loop of going through Lookback API data. In SDK 1.x we used to have RallyDataSource.getRallyObject, which we could use to fetch a single object. In SDK 2.0 I couldn't find any such function. Any other way to accomplish this in SDK 2.0?
