"Unsaved Changes" message after some AddNew in Inserted method

Question

A Javascript SaveChange call calls the server side Inserted method.
This is fine.
In the Inserted method, I call some AddNew methods again.
At the end of the execution, when trying to go to some other screen, I get the "Unsaved Changes" message. If I click "Save Change", the server side Inserted method is executed again.
How can I get rid of this "Unsaved Changes" message? And why did I get it?

I believe the problem is that you are trying to use the ServerApplicationContext from within a method exposed by LightSwitch.  I don't think you can do that, and better yet, you don't need to because you already have access to the server context from
inside those methods (Inserting, Inserted, Can_Insert, etc.).  You can just use the normal api from those methods:
var x = this.DataWorkspace.ApplicationData.TestRecords.AddNew();
Server Application Context is used to access the server context from outside of LightSwitch exposed methods.  For example, you would use the SAC api if you needed to access LS data from inside a web api controller.
When properly using the SAC api from outside of LightSwitch exposed methods,
this thread will tell you all you need to know regarding .Current() vs. CreateContext() and how to properly dispose the SAC.
