Tip: Interface patterns give you an opportunity to explore different interface designs. Be sure to check out How to Adapt a Pattern for Your Application.
Allows the user to change data directly in a grid, and validate a various entries.
This design pattern is not recommended for offline interfaces because reflecting immediate changes in an interface based on user interaction requires a connection to the server.
In this case, the recipe validates for a relevant phone number standard as well as non-sensical dates for existing employees.
