Can someone provide me with a simple example of doing this? I want to load parent and child records all at once and bind to them. I have it working now with just the parent records but whenever I try to click the plus sign to view the child records I get cryptic errors like "0x800a138f - JavaScript runtime error: Unable to get property 'length' of undefined or null reference". The JSON is definitely returning correctly but I'm not sure what the grid is unhappy about.
I have been looking through the Ignite UI examples but haven't been able to get this working.
