More investigation is needed.

1. Do you see any error in the browser console?
2. What data do you see if you try to access the XData server directly, through the URL API?

Hi, Access Violation is a hard guess. It can be something in your database connection. How complex is your application? Can you provide parts of the code here, specially the entity class declaration and the database connection configuration?
